Top-class, unparalleled tailoring

All parts are made from two thin pieces of leather pasted together into a single piece. Using a technique that is said to be the ultimate luxury in leather products , it achieves both strength and thinness . It takes a wealth of experience and skill to create a finish that looks like a single piece of leather without lifting or bending when folded.

In pursuit of simplicity, the engraving is hidden under the card.

thin details

For the ends, overlap the leather and sew on the outside. This is because we are particular about "thinness". If you fold the leather and roll it inside, you can make it smaller, but the leather will overlap and become thicker.
The details are faithful to the ideal of a thin wallet.

Edge comparison - HITOE FOLD ARIA

While pursuing thinness, the leather is sufficiently thick , and we value the textures typical of leather, such as tension and stiffness.

Inner hook without metal fittings

A new idea of ​​using the stored cards as clasps

We devised an inner hook (patented) that hangs on cards instead of on the outside of the wallet.
The smart leather hook keeps the wallet thin and invisible from the outside .
This idea made possible the minimal design of the Hitoe® Fold Aria, a small, thin wallet without hardware .

Not only does it act as a clasp, but it also prevents the card from falling when you carry it.

Preventing cards from falling - HITOE FOLD ARIA
Fits inside to prevent cards from falling accidentally

Sandwiched with leather. But that's it.

Flat appearance just sandwiched between leather. There are no unnecessary parts such as metal fittings or flaps protruding, so it remains thin and won't get caught in your pocket.
It is designed so that the inner hook will not come off when turned inside out . Therefore, there is no need to worry about accidentally opening the top or bottom and dropping coins.

Constructed only from leather without using any hardware

Minimal and smooth operation

It can be easily opened and closed by bending it into the dogleg shape, which is where the name "Fold" comes from. With this one action, you can smoothly insert and remove coins and cards while keeping the wallet vertical.

(If you are right-handed) The trick is to bend the bottom of the wallet in a dogleg shape with your left hand and avoid touching the inner hook.

Leave the banknotes as they are without folding them

Just insert the banknotes without folding them . High visibility and easy to take out. There are no creases or tri-folds , so it fits smoothly into vending machines and self-checkout machines.
The bill holder has a continuous design with the inner hook. The curve acts as a guide, allowing you to insert and remove it smoothly without getting caught .

You can smoothly put in and take out bills without touching the bill holder.

Prevent cards from falling

When closed, the inner hook hangs on the card so it won't fall . Adopts a slipless design (patent pending) that prevents cards from falling even when the wallet is open.
The feeling of sliding the card is of high quality, and it is comfortable to put in and take out the card.

Effects of slipless specification (patent pending)

Use temporary cards as billholders . There is no problem with opening and closing the wallet.

Temporary cards can be used as billholders

Smooth and overflowing coin pocket

The coin pocket is shallow and has no metal fittings such as zippers or hooks, so you can quickly take out the coins you need.
When storing the coin pocket, the lid of the coin pocket acts as a guide for smooth storage.
Also, if you close your wallet, the coins will not overflow. Even when the coin pocket is open, the lid of the coin pocket prevents it from overflowing.
There is plenty of room even if you put in 999 yen worth (15 pieces).

Design that follows the laws of nature

“Why is the golden ratio beautiful?”
The golden ratio of 1:1.62 is the aspect ratio of a rectangle with spiral repeating squares whose sides are the Fibonacci sequence . (Figure below)
In fact, the Fibonacci sequence is hidden everywhere in nature. The branches of trees, the number of petals, sunflower seeds, seashells, typhoons, spiral galaxies. It can also be found in art of the utmost beauty, such as the pyramids, the Parthenon, and the 36 Views of Mt.
The important thing is not to achieve the golden ratio. Proportions from the details to the whole follow the Fibonacci sequence , which is deeply related to nature and the providence of life, resulting in a well-balanced design that resonates with the heart .

Can be used beautifully for a long time

In general, most problems with wallets are caused by hardware or sewing. However, Hitoe® Fold, a small, thin wallet, uses no hardware and only has four stitches .
Furthermore, the corners that are easily damaged are layered with outer leather and inner leather to increase durability. The seam allowance is extremely small, making it a design that won't lose its shape even in a pants pocket .
