Product Features
A Gold Foil Interior with a Subtle, Refined Radiance
A new gold foil model joins the much-loved compact wallet series, UNO ver.2, now elevated with an elegant, understated shimmer.
The exterior and lining are crafted from premium Meteor Leather, selected for its exceptional quality and finish.
Further details on the leather can be found in the middle section of this page.
Defined by its fine grain and softly lustrous champagne gold tone, this material brings a quiet sophistication—adding a refined presence to your everyday carry, as well as to more formal occasions.
Three Key Features
1. A Truly Minimal Size
“The physical limit is 16.3 cm.”
Comparable in length to an iPhone Plus, the Uno series was not developed by simply trying to shrink the conventional 20 cm wallet.
Instead, we began with a different question:
If the longest Japanese banknote measures 16 cm, what is the absolute minimum length a long wallet can physically be?
The answer is 16.3 cm (6.42 in)—just 0.3 cm (0.12 in) longer than a 10,000-yen note (16.0 cm / 6.30 in).
Born from this unconventional approach, the Uno series achieves an extreme, near-limit size while preserving exceptional ease of use.
As long as the size of Japanese banknotes remains the same, we believe this represents the true physical limit—dimensions that challenge the very concept of what a long wallet should be.
Take a moment to measure the length of your current wallet.
You may be surprised at the difference..
That Achieves an Astonishingly Compact Size
In simple terms, we “eliminated stitching.”
To achieve this extreme minimal length, we could not apply stitching along the section that forms the bill compartment. Stitching inevitably requires additional material allowance for seams—no matter how small.
Even a few millimeters of seam allowance would increase the overall length. By rethinking conventional construction and removing this constraint, we were able to realize a truly near-limit size.
The Uno series does not use stitching in the bill compartment.
Instead of sewing, the leather is precisely folded and secured with a snap closure—allowing us to achieve a clean, streamlined design without adding bulk.
This unconventional construction makes a remarkable difference.
Compared to standard long wallets, it is approximately 3–4 cm (about 1.2–1.6 inches) shorter in length. Even when placed beside so-called “minimal” long wallets on the market, it is over 1 cm (about 0.4 inches) smaller.
By rethinking traditional wallet construction, the Uno series achieves a level of compactness that truly stands apart.
*Please note: Comparisons with standard wallets and so-called “minimal” long wallets are based on our own research.
2. Exceptionally Compact — Yet Slim and Spacious
At this point, it may seem that this is simply a wallet designed with size reduction in mind. However, we understand that being small alone is not enough to end your search for the perfect wallet.
The Uno ver.2 is not only exceptionally compact—it is also slim and highly functional in capacity.
Even at full capacity—holding up to 13 cards, 30 coins, and 30 bills—the central thickness measures just 18 mm (approximately 0.7 inches).
Compact in size, yet designed to carry more than you would expect.
Even at its thickest point—the coin compartment—the wallet measures only approximately 25 mm (about 1.0 inch).
How is it possible to achieve what seems like a contradiction:
“compact and slim” × “large capacity”?
The answer lies in the structure.
The primary factors that add bulk to a wallet are the overlapping of cards and the internal dividers between them.
First, in this design, the cards are arranged vertically. The structure ensures that no more than three cards overlap at any given point.
In many conventional wallets, cards are stacked horizontally, often overlapping five to six cards in thickness. This layered construction significantly increases overall bulk.
Second, consider the dividers used to separate each card.
In this product, there are no traditional dividers at all.
Instead, cards are inserted into precisely angled slits, allowing each card to be stored independently without the need for layered partitions. In typical wallets, dividers are placed between every card slot—adding unnecessary thickness with each layer.
By eliminating both excessive overlap and internal partitions, the Uno series achieves remarkable slimness without compromising capacity.
3. Exceptionally Easy to Use
While we have emphasized size and capacity, the most important element of any wallet is usability.
The Uno series is designed with independently structured card slots, allowing you to instantly locate the card you need—and remove it just as quickly.
Efficiency is built into the structure itself, ensuring smooth, intuitive access every time you reach for it.
The three-dimensional structure of the bill storage section allows for smooth insertion and removal of bills.
The three-dimensional structure of the bill storage section allows for smooth insertion and removal of bills.
By placing your IC card in its dedicated slot, interference with other cards is minimized—allowing you to pass through ticket gates seamlessly without removing it from the wallet.
The multi-purpose storage pocket can accommodate small essentials such as keys or an AirTag. It is also ideal for carrying everyday items like medication or a personal charm.
The Plus model is the highest-grade offering in the UNO series.
The UNO ver.2 is available in two versions: the standard model and the upgraded “Plus” model. This product is the Plus version.
Four Exclusive Features of the Plus Model
1. Fully Lined, Double-Layer Construction (Musō Finish)
In the standard version of UNO, the reverse side of the exterior leather (the flesh side) is left unlined.
The Plus version, however, features a fully lined construction using the same leather as the exterior, creating a clean, refined finish.
This double-layer structure not only enhances the overall appearance but also significantly improves durability, especially in areas that experience the most stress during daily use.
Because this construction requires additional leather as well as extra bonding and stitching processes, the Plus version is priced higher than the standard model.
That said, we are confident it delivers value well beyond the difference in price.
Even with the addition of a lining layer—resulting in a double-layer leather construction—the overall slimness remains unchanged.
In the standard model, the exterior is made from a single piece of leather approximately 1.5 mm (0.06 inches) thick.
In the Plus model, two thinner layers of leather—1.0 mm (0.04 inches) and 0.5 mm (0.02 inches)—are carefully laminated together. As a result, the finished thickness remains approximately 1.5 mm (0.06 inches), the same as the standard model.
Achieving this requires additional skiving (leather thinning) processes, increasing both time and craftsmanship involved—but this meticulous attention to detail is one of the defining qualities of the Plus model.
3. Meticulously Finished Edges (Edge Painting)
The finishing process applied to the cut edges of leather is known as edge painting.
In the standard model, a clear edge paint is intentionally used to preserve the natural character and texture of the leather.
In contrast, the Plus model uses custom-mixed edge paint carefully matched to the color of the leather itself. This results in a smoother feel, a more refined and polished appearance, and enhanced durability at the edges.
4. New Logo Design with Foil Stamping
On the Plus model, the logo is finished with gold foil stamping, creating a more refined and luxurious appearance (Silver foil is used for the Graphite × Gold version).
Renewed Zipper Design
This model features a newly updated zipper with an original zipper engraved with the MOKU logo.
Beyond functionality, this special specification reflects our dedication to beauty and brand identity, down to the finest details.
The zipper is designed to open only when intentionally pulled, incorporating a lock function that helps prevent accidental opening while inside a bag. This ensures added security and peace of mind during daily use.
Let this be the wallet that ends your search.
We often hear from customers who are already using a moku wallet:
“I’ve tried many compact wallets, but this was the right answer in wallet design.”
There may be no greater compliment. It truly means the world to us.
Another phrase we frequently receive is, “Once you start using it, you can’t go back.”
We invite you to experience it for yourself—and discover why so many feel the same.t to go back.
Proven Usability, Refined in the Uno Series
This product was developed as an upgraded model of the original Small & Slim Long Wallet Uno, which debuted in January 2023.
At its launch, the original Uno received support from 430 backers through crowdfunding. On our official online store, it continues to maintain a strong average rating of 4.7 out of 5, reflecting the high level of customer satisfaction.
Record-Breaking Results in Crowdfunding Pre-Launch
From July 15 to September 29, 2024, this model was offered in an exclusive pre-launch campaign on Makuake, a leading Japanese crowdfunding platform.
During the 75-day campaign period, we received pre-orders from 852 supporters, totaling ¥22,569,600 (approximately $150,000 USD) in sales.
The overwhelming response reaffirmed the strong demand for a wallet that balances compact design with uncompromising usability.
Three Key Improvements from the Previous Model
1. Increased Capacity — Virtually the Same Overall Size
The storage capacity has been significantly enhanced while maintaining smooth and effortless access.
Previous Model:
– 7 cards
– 20 coins
– 20 bills
Current Model:
– 13 cards
– 25 coins
– 25 bills
Despite this substantial increase in capacity, the overall size remains almost unchanged.
The shorter side has increased by just 1 mm (approximately 0.04 inches)—a difference barely noticeable in everyday use.
Greater capacity, without compromising its carefully balanced proportions.
Left: Previous Model
Right: Current Model
The key to this enhanced capacity lies in a refined internal structure.
Among the feedback we received on the previous model, the most common request was for greater coin storage. This improvement became our primary focus.We successfully expanded the coin compartment both vertically and horizontally, significantly increasing its usable space.
The zipper has been extended by 1.5 cm (approximately 0.6 inches), resulting in a noticeably wider opening. While the numerical difference may seem small, the impact in daily use is substantial—the improved accessibility is immediately apparent.nificant that it's surprisingly easy to use.
When comparing both models with 25 coins inserted, the difference is visually clear. The previous model appears tightly filled, whereas the current version maintains a clean, composed silhouette with minimal bulging.
2. Stitch Lines Concealed for a More Refined Design
Left: Previous Model
Right: Current Model
In this model, an additional layer of leather has been carefully incorporated to conceal the stitched edges.
While this adds the thickness of a single leather layer, it allows the seam lines to be fully hidden—resulting in a cleaner, more sophisticated appearance.
The structure feels more cohesive and thoughtfully finished, enhancing the overall refinement of the design.
3. Added Storage for Everyday Essentials
A newly added pocket provides convenient space for receipts, small documents, or point cards—keeping frequently used items neatly organized.
The compartment is also designed to accommodate banknotes up to the size of a 1,000-yen note (76 mm × 150 mm / 2.99 in × 5.91 in).
Premium, Eco-Conscious Materials
① Materials with a texture so rich, you can’t help but touch them.
② Materials that contribute to a more sustainable future — simply by choosing them.
We carefully select materials that embody both.
Material: Meteor Leather
Crafted from domestically sourced cowhide, Meteor Leather offers a balance of softness and durability.
Its chrome-tanned finish delivers a refined appearance, enhanced by a finely grained texture that lends depth and character.
A delicate foil treatment is applied to the surface, introducing a subtle yet sophisticated metallic sheen.
Compared to leathers such as Pueblo and Buttero, its aging process is more gradual—making it an ideal choice for those who wish to enjoy its original beauty for an extended period.
A Material Choice That Supports a More Sustainable World
Much of genuine leather is made from animal hides that would otherwise be discarded as byproducts of the food industry. By utilizing these hides, leather production is often considered more environmentally responsible than disposing of them unused.
In pursuit of texture and durability, many leather production processes rely heavily on chemical agents and additives, which can generate environmentally harmful byproducts during manufacturing.
By contrast, there are leathers processed using plant-derived ingredients. One such method is full vegetable tanning, which uses tannins—naturally occurring polyphenols found in plants.
At MOKU, we primarily work with leathers tanned using this traditional, vegetable-based approach.
Everyday Use Scenarios
Carry it in your pocket and head out hands-free
Pass through ticket gates effortlessly — works with your IC card inside.

*When placed in the independently designed single-card pocket inside UNO, IC cards can be used directly without removing them.
Designed for Use Worldwide
Compatible with most banknotes used around the world.
For reference, the Japanese ¥10,000 banknote—often considered relatively large—measures 76 mm × 160 mm (3.0 in × 6.3 in).
As shown below, it fits comfortably in the wallet with ample room to spare.
