HITOE Fold Aria

The ultimate in functional beauty

"HITOE® Fold" has established the highest amount of crowdfunding (*) for wallet in Japan by collecting more than 1200 pieces of support in just 5 minutes. (* As of December 17, 2020)
The topical work is even thinner, smaller, lighter, stronger, and easier to use, and is now available in the "ARIA" series.
With its sophisticated design and exquisite chraftsmanship, it has been sublimated into a breathtakingly complete functional beauty.
You can choose right-handed or left-handed.

What is HITOE® FOLD?

Appearance of HITOE Fold Aria

"Go out lightly without a bag!"
 The HITOE® series was created to make this wish come true.
It was made in pursuit of minimalism, ease of use and high-capacity storage suitable for a cashless society.

Light as air "ARIA"

Comparison of HITOE Fold and hand size

"ARIA" which means "Air" in Italian. It also means singing song lyrically in opera and religious music.
HITOE® FOLD ARIA wallet is thin and light as air yet beautiful and very original.
All parts are made by gluing two layers of ultra-thin leather together.

This technique is said to be one of the highest luxuries in leather products, making them stronger, lighter, and thinner.
The white powder on the surface leather is a wax called bloom. The more you use it, the more it rubs and penetrates, giving you a transparent look.

The interior leather is the same color leather that has not been waxed. When it's opened, it shows a beautiful gradation with the exterior.

"HITOE® (Single layer) Structure"

Conventional wallets get thicker because the cards and coins overlap. The solution to this is "HITOE® (Single layer) Structure". It prevents cards and coins from overlapping. And there are only 4~5 layers of leather overlapping each other.
Even when storing 5 bills and 5 cards, this wallet will be only 10mm-thin. It is also extremely light - only about 33g.

Commitment to design

1 "Perfection is achieved when there is nothing left to take away."

This is the word of Saint-Exupery, the author of "The Little Prince".
Reduce the elements as much as possible and make the rest directly related to usability. This is the "perfection" we aim for.

- Smoothly opening and closing.
- Easy to insert and remove the contents.
- Thinness that you'll forget it's even in your pocket.

The simple design and comfortable use of HITOE® FOLD ARIA has reached the stage of perfection.

Minimal design

2 Pursuit of thinness

If we change the "seam allowance", which is a feature of the appearance, to "roll-in", we can reduce the size by about 2 mm. Still, the reason for using "seam allowance" instead of "rolled-in" is to achieve thinness.
"Roll-in" is inconsistent with the concept of this wallet "thinness", because the leather overlaps each other and becomes thicker.Highlighting the concept gave it a dignified appearance.

3 Design based on natural order

"Why is the golden ratio beautiful?"
The golden ratio is a rectangle that spirally repeats a square with a Fibonacci sequence (1 2 3 5 8 13 21 ...) as one side. It converges to about 1: 1.618.
And this sequence is hidden everywhere in nature. Tree branches, blood vessel branches, number of petals, sunflower seeds.
The spiral shape that connects the vertices can be found not only in shells, typhoons, spiral galaxies, but also in the most beautiful arts such as the pyramids, the Parthenon, and the Thirty-six Views of Mt. Fuji by Katsushika Hokusai.
Since it is deeply related to the natural order and nature of life, the golden ratio based on the Fibonacci sequence will touch the heartstrings of us.
It is not important to use the golden ratio in each element. By using the Fibonacci sequence as a ratio from details to whole, it becomes well-proportioned design which resonates in our heart.

Seven well-thought-out usability

It's not just thin and compact. We also pursued usability so that each movement can be completed with the least amount of action.

1 New idea to use stored cards

We invented the "Corner holder" that hooks onto the cards to be stored. (Patent in process)
It keeps the flap closed while preventing the cards from falling out unexpectedly.

It looks like the flap is closed Firmly prevents unexpected card drops

2 No metal parts, only leather

Nothing extra sticks out, such as metal parts or bands, so there is no catching in your pocket and clothes are never damaged.

3 Smoothly opening and closing

You can easily open the wallet by bending the border of the cards and coins into a "dogleg" shape. By this one action, you can access your coins, bills, and cards for quick checkout.

4 Without folding bills

Just insert bills without folding them. It has high visiblity and is easy to take out.
It is compatible with a variety of bills, including dollars, euros, and Japanese yen.

5 Card pocket

It is easy to insert and remove cards as your fingers can go deep inside.
It can hold up to six cards.

Card pocket that is smooth not only to put out but also to put in

6 Shallow coin pocket

With a shallow coin pocket, you can quickly find the coin you need and quickly remove it. When the wallet is closed, the coins will not spill.
It can hold up to about 15 coins.

Coins do not overflow when in use

7 High durability

Most problems about wallets are caused by metal parts or sewing. No metal parts are used and there are only 3 pieces to sew. In addition, we avoid sewing on edges, bends and other easily damaged areas.
So you can use it for a long time.

For " Aria ", use thin leather "solid paste (entire surface glue)".
With the technique that is said to be the best luxury of leather products, two thinly strained leathers are glued together to make it stronger, lighter and thinner.
It takes a wealth of experience and skill to finish two thin pieces of leather without floating or bending when folded, giving the illusion of one piece.
Since no core material is used, the characteristics of leather vary greatly in units of 0.1 mm. In addition, the combination of leather to be bonded gives a different feeling of tension, from soft texture to strong elasticity.

Specifications are determined by repeating trial and error with various materials and thicknesses.

About aging

The leather used for the outer leather is tannin tanned double shoulder leather with white wax processing, and the white powder is wax called bloom. The more you use it, the more the wax on the surface rubs and penetrates, giving a transparent look.
The interior leather is the same color leather that has not been waxed. With a fine grained surface, it creates a beautiful gradation with the exterior when opened.

The shoulder is also a part that contains a lot of loose scratches, uneven color, blood lines and tigers (wrinkles), and you can enjoy the expression unique to natural leather.
It contains enough oil and wax, so no special maintenance is required.
The surface is delicate and vulnerable, but you don't have to be overly nervous. By picking it up and using it regularly, you will be able to get used to scratches and stains as well as deepening the color and luster.

"HITOE® FOLD ARIA" is a flagship model that pursues materials, design, functionality, all without compromise. "HITOE® FOLD" has realized the concept with thick leather that allows you to enjoy the texture and aging of leather.

1 Material

"HITOE® FOLD" utilizes the characteristics of leather as it is and uses high quality thick leather. The leather floor (back side) is processed to prevent fluffing in order to make banknotes slippery.

"HITOE® FOLD ARIA" is both thin and durable by laminating thinly strained leather and making both sides silver. When you pick it up, it has a light finish.

Usage state seen from an angle Left: Liscio Right: Aria

2 sizes

"HITOE® FOLD ARIA" is about 2mm smaller in width than "HITOE® FOLD".

In both cases, the maximum number of leather layers is 5, but the total thickness of the leather is about 1 mm thinner for "HITOE® FOLD ARIA".

Palm size Palm size

3 configurations

"HITOE® FOLD" has 5 parts and 5 stitches.

"HITOE® FOLD ARIA" has 3 parts and only 3 stitches.

The difference is the presence or absence of stitches on the side of the wallet, and when loading and unloading banknotes from the side, "HITOE® FOLD" may feel stuck in the stitches compared to the smoothness of "HITOE® FOLD ARIA".

Q. Do you have any tips for opening and closing?
A. You can use it smoothly if you bend the boundary between the coin and the card into a "<" shape. When closing, hold the lid from above and bend it in a "<" shape, and the triangular leather will hang on the card. The trick is not to touch the triangular leather.

Q. When I close it, it gets distorted.
A. The cause is the misuse of hanging triangular leather on the outside of the wallet. Please use it by hanging it only on the card.

Q. Will coins overflow?
A. Coins will not overflow when the wallet is closed. Even when opened or slightly downward, the coin pocket lid keeps coins in place and does not overflow.

Q. What should I do with the receipt?
A. Please store the receipts under the banknotes.

The cows that are the source of this leather are grazing and bred so that they can grow healthy without stress. This leather has a delicate finish so that you can enjoy the original charm of high-quality leather. Therefore, "living proof (natural mark)" such as wrinkles and scratch marks that originally existed may be engraved. The Natural Mark is a proof of good quality natural leather, and as you use it, it becomes the unique taste of the product.

Rose wound / bloodline


It is a trace of a small scratch or insect bite when bumping or fighting. The more you grow up in an environment closer to nature, the more you grow. Depth, length, and size vary depending on the individual.


It is often found after blood vessels, especially on the floor.



It is a trace of deep wrinkles that are often seen from around the neck to along the spine. Italian leather is popular because it is said that the more tigers there are, the more beautiful it is. The fiber density around the spine is the highest, and there is no problem with strength.

Color unevenness

Color unevenness

Color unevenness may occur due to differences in fiber density. Due to the unevenness of the leather quality, it is unavoidable as long as the leather is a natural material.
Please note that it is the one and only individuality of leather.

If SYRINX products are used for their original purpose within the bounds of common sense, there is a one-year warranty period from the date of purchase regarding material and structural defects.
