This is the Hitoe® Fold Aria 2021 model, from the previous generation.
There are two differences from the latest model.
The first is the finishing of the edges of the coin pocket and card pockets.
The second is a difference in width of about 3mm.
"Aria" - Italian for "air" and a beautiful solo vocal piece.
As its name suggests, it is a light, thin, and beautiful wallet that you'll forget is even there.
“Foschia” means “fog” in Italian. This leather is characterized by its white, misty waxed finish, reminiscent of a morning fog.
As you use it, the wax gradually absorbs into the leather, revealing a clear and elegant sheen.
A patented technology based on the innovative idea of using the card itself as a clasp. By eliminating all metal fittings, a thin, flat design was achieved. Coins won't accidentally spill out because the wallet won't open if the front and back are confused.
The "Hitoe® structure" arranges cards, coins, and bills side by side without overlapping, achieving surprising thinness without sacrificing storage capacity. The leather overlap is also kept to a maximum of 5 layers.
Even with 10 bills, 15 coins, and 6 cards, the thickness is only 12mm※.
※ Thickest part excluding the coin pocket
"Double-faced tailoring" involves bonding two pieces of leather to create the smooth feel of a single piece. This tailoring, which combines durability and elegance, embodies the exquisite and skilled craftsmanship of artisans.
Cards can always be inserted and removed smoothly, yet they are less likely to fall out accidentally.
"Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away." - Antoine de Saint-Exupéry
Through refined design and exquisite craftsmanship, we pursued thinness, lightness, and functional beauty.
We incorporated the beautiful harmony of the natural world, as depicted by the Fibonacci sequence, into the proportions of the wallet.
Each time you hold it, you'll feel a balanced beauty that resonates with your heart.
Delicate stitching, carefully polished leather edges, and fine lines along the borders.
The aesthetic details elevate the wallet's presence.
The leather is stitched on the outside to minimize overlap.
This detail is faithful to our ideal.
No metal fittings, no flaps. Just a simple design where leather holds everything together. Its simplicity means it won't snag, allowing you to carry it smartly anywhere.
With no metal fittings, the stitching is placed in positions that are less prone to fraying.
Vulnerable corners are reinforced with overlapping leather, enhancing durability.
Furthermore, the seam allowances are kept to a minimum, and the design resists distortion even when carried in a pocket.
Just bend the wallet into a "V" shape. Bills and cards can be retrieved instantly.
Payments at the register become smoother and more stylish.
Bills can be stored unfolded. No creases, making them easy to use in vending machines and self-checkout counters.
The bill stopper part can store cards you don't usually use. It doesn't affect the wallet's opening and closing, and retrieval remains easy.
The coin pocket features a simple design without zippers or snaps. Its shallow pocket and short flap make it easy to access coins and prevent them from spilling. It can hold 15 coins (¥999) or more.
Surprisingly, many currencies around the world are larger than Japan’s ¥10,000 bill or ¥500 coin.
This wallet accommodates most of them, making it comfortable to use even when traveling abroad.
So thin you'll forget it's even in your pocket.
Make a minimalist choice that lightens your heart in your daily life.
Foschia, meaning "fog" in Italian, is characterized by its white wax-covered appearance, reminiscent of morning mist. As it is used, the wax permeates the leather, revealing a translucent finish.
Made from bovine shoulder leather sourced from Northern Europe. After vegetable tanning, the surface is lightly buffed (polished) and then coated with white wax.
Natural marks may also be visible.
LWG (Leather Working Group) Environmental Certification Gold Rank.
As the wax gradually permeates, an elegant and natural sheen develops. Oil care is not required unless scratches or dryness are a concern. For more details, please refer to here.
Light colors have a delicate surface and are prone to visible stains and scratches, requiring careful handling.

※ Due to monitor settings, and differences in dye absorption depending on the condition and part of the raw hide, and the season, there may be slight variations between the displayed color and the actual color.
About Scuff Marks
Where the white wax is rubbed, the natural color of the leather appears, making it look darker and temporarily like fine scratches. As the wax permeates during regular use, the initial marks will gradually fade, and the leather will be covered with a translucent sheen.
During production and packpatina, minor scuffs and pressure marks may occur, resulting in individual variations in how the wax remains initially. Rest assured, the leather itself is not damaged, and these variations will become uniform as patina progresses.
About Wrinkles
Due to the wax, Foschia leather tends to wrinkle easily on the surface when bent sharply. As it is used, these wrinkles will be covered with a sheen, and the texture will gradually settle.
The video below shows an example where the entire leather was intentionally wrinkled and then used for about a month in a back pocket of trousers. The luster increases, and the wrinkle patterns develop a subdued character.
The Hitoe® Fold series has received a total of 20 awards, including the three major global design awards: iF Design Award (Germany), Red Dot Award (Germany), and IDEA (USA), as well as the Chicago Good Design (USA) and German Design Awards (Germany). It has been highly praised for its minimalist design and comfortable usability.

To open and close the wallet smoothly, follow these steps:
【To open】Bend the boundary between the coin pocket and card pocket into a "V" shape, and the inner hook will naturally disengage. There is no need to touch the inner hook directly.
【To close】While gently pressing the top, bend it into a "V" shape using the same method, and the inner hook will naturally catch on the cards.
This is because the inner hook is hooked to the outside of the wallet. Please make sure it only hooks to the cards stored inside.

To prevent the card pockets from becoming too loose, they are designed to be a bit snug, and may feel tight at first. Over time, they will gradually adapt to your usage and become easier to remove.
If it feels too tight initially, try inserting and removing one fewer card a few times to break in the leather before regular use.
When the wallet is closed, the inner hook engages with the cards, preventing them from falling out.
Even when open, the cards are unlikely to fall out due to the anti-slip treatment applied.
The Hitoe® Fold Aria and Hitoe® Fold Less, with their slipless design (patent pending), are even more resistant to cards falling out.
Please note that if the wallet is laid horizontally, the anti-slip effect will be reduced as shown in the video.
The wallet has a lid that prevents coins from spilling, so coins will not spill out during normal use. As the leather breaks in, it will become even more stable.
Please note that this wallet has a vertical design, so if you open it horizontally like a typical bi-fold wallet, coins are more likely to spill out.
When putting the wallet in your pocket, storing it so that the coin pocket is vertical will reduce the sound of coins. It also makes it easier for coins to align automatically.
Rest assured, if you turn the wallet inside out, the inner hook will not disengage and the wallet will not open.
You can identify the front side as follows (for right-handed users):
Please choose based on the hand you use to handle money and cards.
Modern magnetic stripes have strong magnetic resistance, so stacking them is not an issue. Also, it does not affect IC chips.
However, older magnetic cards may have weaker magnetism, so to be safe, we recommend storing them with the magnetic stripes facing different directions to prevent them from overlapping.
