Toward perfected functional beauty

I want to go out without any bag! In order to fulfill this desire, we have developed the "Hitoe® Fold," a small, thin wallet that does not overlap with cards and coins. Hitoe® Fold," a small, thin wallet with no overlapping cards and coins, was born. was born.
Aria" is the ultimate in thinness.

Aria" is as light as air.


Aria" means "air" in Italian. It is a light wallet that, like air, you forget it even exists.

Hitoe® structure" stands out for its thinness.

Well-honed design

1 "Perfection is a state in which no further sharpening is possible.

These are the words of Saint-Exupéry, the author of "The Prince of Wales.
Hitoe® Fold Aria's simplicity of design and comfort are the height of perfection: smooth opening and closing without hardware, easy entry and exit, and a thinness that makes you forget it's even in your pocket.

2 Wallets this thin

The edges are not "rolled in" but have a "seam allowance". This is in pursuit of "thinness. If the edges are rolled in, the size will be smaller, but the overlap of the leather will increase and it will become thicker.
This detail is faithful to the ideal we are aiming for.

端部比較 - HITOE FOLD ARIA Size comparison by edge treatment method

Even in pursuit of thinness, the leather is thick enough, and the texture of tension and firmness are also important.

3 Beautiful details

Precise and delicate stitching, transparently polished koba (cross-section of leather) that reveals the overlapping layers of leather, and thin lines (nenpiki) drawn around the edges with a heated iron. Even the koba of suede, which is said to be impossible to polish, is polished with great care, pursuing beauty down to the smallest detail.

4. Top quality manufacturing method

All parts are made of thin leather with a "sticky" (glued all over ) finish. This technique is said to be the highest luxury of leather products. Two pieces of thinly stripped leather are pasted together to create a stronger, lighter, and thinner finish. It takes a great deal of experience and skill to create a product that looks like a single piece of leather, even when folded without lifting or flexing.

刻印 - HITOE FOLD ARIA Pursuing simplicity, the engraving is hidden under the card.

5 Long and beautiful use

Most problems with wallets are caused by hardware and sewing. No hardware is used at all, and only four stitches are used.
In addition, the corners, which are prone to pain, are made more durable by layering the outer and inner leather. The seam allowance is as small as possible, and the design prevents the bag from losing its shape even when used in the back pocket of trousers.
It is a simple and sturdy construction that can be used beautifully for a long time.

角の補強 - HITOE FOLD ARIA The corners are layered with leather for durability.

6 Design in accordance with the providence of nature

Why is the Golden Ratio so beautiful?
The golden ratio 1:1.618 is based on the Fibonacci sequence is the ratio of the length and width of a rectangle consisting of a square with the Fibonacci sequence as one of its sides repeated in a spiral shape. (see figure below).
The Fibonacci sequence is hidden everywhere in nature. Tree branches, the number of petals, sunflower seeds, shells, typhoons. Even in the art of beauty, such as the Pyramids, the Parthenon, and the 36 Views of Mount Fuji.
It is not important to achieve the golden ratio. It is the Fibonacci sequence, in which the proportions from the smallest detail to the whole are deeply related to the providence of nature and life, that results in a harmonious design that resonates with the heart.

Not only is it thin and small, but it is also comfortable. We pursue not only ease of use but also comfort.

Difference 5: Feel of use
Depending on the stitching on the side of the bill holder, the "Hitoe Fold" may feel a little scratchy when inserting or removing bills from the side. Also, the sliding of banknotes may cause more friction.
The "Hitoe Fold Aria" and " Hitoe Fold Less" have a card pocket that is designed to prevent the card from falling out even when the clasp is removed.

Q. Do you have any tips for opening and closing?

A. If you bend the border between the coin and the card in a "ku" shape, the hook on the card will come off and you can use the card smoothly.

To close the cardholder's wallet, gently press down on the top of the flap and bend the flap in a "ku" shape so that the hook will naturally fit over the card. The trick is to keep your fingers away from the hook.

To close, simply slide it while holding it down (e.g. Hitoe Fold).

Q. When I close it, it is distorted.

This is caused by misuse of the hook on the outside of the wallet. Please hang the hook only on the card to be stored.

(ex. Hitoe Fold)

Q. Will coins or cards overflow?

A. No. If the wallet is closed by placing the hooks over the cards to be stored, there will be no overflow of coins or cards. When the wallet is opened, the lid of the coin pocket will hold the coins in place, preventing them from overflowing. However, if the wallet is used horizontally, there is a possibility that coins will overflow. Please use the wallet in portrait orientation.
