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 9mm-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.

To close it, just slide it while holding it down.

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.

Made in TOKYO

This wallet is manufactured at a long-established leather factory with the highest level of solid-pasting technology. The finish looks like a single layer of leather.
In addition, the leather is laminated under high pressure of more than a dozen tons. The edges are polished clear and fine lines are added with a heated iron.
From design to production, we do everything in Tokyo and deliver the world-class "Made in TOKYO" quality.

Intellectual property protection efforts

"HITOE® FOLD ARIA" has obtained three design registrations in Japan and has applied for one patent. Furthermore, with a view to global expansion, we have applied for international design registrations in the United States, Europe, China, Taiwan, South Korea, Australia, etc.

The joy of opening the box

We will deliver it in a special just-sized box that can be used even during storage. It is also ideal for gifts.

Perfect size vanity case

手のひらサイズ Left: Hitoe Fold (5 cards) Middle: Hitoe Fold Aria (5 cards) Right: Hitoe Fold Less (3 cards)

Difference 5: Feel of use
Depending on the presence or absence of stitching on the side of the bill holder, the Hitoe Fold may feel a little scratchy when inserting or removing banknotes 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.

Foggy look

Foschia is the Italian word for "fog.
This vegetable-tanned double shoulder leather is white-waxed to give it the look of a morning mist.
The more it is used, the more it rubs and permeates, giving it a translucent look.

The tanning material is made from the fruit of the tara plant, which is a legume native to South America.
It is rare and expensive, but it has the lightest color and lightfastness among vegetable tannins.
Since the leather can be tanned whiter than usual, the beautiful light color is achieved using only dyes, not pigments.


Shoulder is also the part of the leather that contains many rose scars, uneven colors, blood streaks, and wrinkles, and you can enjoy the unique expression of natural leather.

The surface is delicate and prone to stains and scratches, but as it is handled and used often, the color and luster will deepen and the leather will become more comfortable.
