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.

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.

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.

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

If you bend the border between the coin pocket and the card pocket in the shape of a "ku", the inner hook will come off and you can use it smoothly.

When closing, gently press down on the top of the pocket while bending it in a "ku" shape, and the inner hook will naturally fit into the card pocket. The trick is to keep your fingers away from the inner hook.

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

Q. It distorts when I close it.

This is caused by misuse of the inner hook on the outside of the wallet. Please use the inner hook only for the cards you wish to store (e.g. Hitoe Fold).

(Example: Hitoe Fold)

Q. Will coins or cards spill?

If you hang the inner hook on the card, neither coins nor cards will spill.
Even when the wallet is open, the lid of the coin pocket prevents coins from spilling. However, there is a possibility of spillage if the wallet is opened and used horizontally. Please use the wallet in portrait orientation.
The non-slip card pockets are designed to prevent cards from falling out when the wallet is open. Please refer to the product description for the specifications of each product.

Q. Should I choose a right-handed or left-handed wallet?

Please choose right-handed if you handle cards or coins with your right hand, or left-handed if you handle them with your left hand.

Q. I am concerned about the sound of coins.

If you store coins in the pocket so that the coin pocket is vertical, you can prevent the sound of coins. Also, coins can be aligned more easily and automatically.

Q. Won't the coins spill out if I mistake the front side for the back side?

A. No. With use, the leather will develop a habit. Also, we have designed the wallet so that it will not open if you mistake the front side for the back side.

Black and White

Monocromo" is the Italian word for monochrome.
The contrast between the two colors is unique: the outer leather is wet-white tanned and grainy white, and the inner leather is smooth black.

The outer leather is barrel-dyed with dye (aniline) and then sprayed with pigment in five separate coats. It is resistant to scratches and stains, repels water, and hardly ages , so it retains its beauty for a long time. Single-bud ( back to waist ). This is the area with the densest fibers and finest texture, which produces a uniform and beautiful grain when grained.
