Hitoe® Fold Aria - Monocromo

Toward perfection and functional beauty

Perfection is the state in which no further cuts can be made."
These are the words of Saint-Exupéry, the author of "The Prince of Stars".

The Hitoe® structure (design registered) that prevents stacking of stored items , the minimalist design and smooth operability without metal fittings with an inner hook (patent pending ), and the slipless specification that prevents cards from falling out (patent pending).

The Hitoe® Fold Aria is the perfection of the Hitoe® Fold series, the ultimate in minimalism in both design and operability.

Sophisticated design and exquisite workmanship have been sublimated into a breathtakingly perfect functional beauty.

Aria" is as light as air.

Aria" means "air" in Italian. Aria Aria" means "air" in Italian.
Like air, you may forget it exists, Aria is a light and thin wallet and so thin that you forget it exists, just like air.

The challenge of thinness

The Hitoe® structure (design registered), which does not stack cards and coins, achieves thinness.
The thickest part when stored is 12mm.
(6 cards, 10 bills, 10 100 yen coins)
・Palm size: 89mm x 91mm
・Light as air: approx. 30g
Can hold up to 15 bills, 20 coins, and 6 cards. Even with ample storage, it remains thin.

Highest quality manufacturing process

All parts are made from two thin pieces of leather pasted together to form a single piece. This technique is considered the highest luxury in leather products, and it is both strong and thin. It takes a wealth of experience and skilled craftsmanship to create a product that looks like a single piece of leather without lifting or deflection even when folded.

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

Thin detailing

The edges are stitched together on the outside, with the leather stacked on top of each other. This is for the sake of "thinness. If the leather is folded over and rolled inside, the size can be reduced, but the leather overlaps and becomes thicker.
This detail is faithful to the ideal of a thin wallet.

Size comparison by edge treatment method

While pursuing thinness, the leather is made thick enough to have a leather-like texture, such as tension and firmness, which is important.

Hardware-free inner hook

A new concept of using the cards to be stored as a clasp.

We have devised a patent-pending inner hook that hangs from the card instead of the outside of the wallet.
The smart leather hook is invisible from the front while the wallet remains thin.
This idea made possible the minimalist, hardware-free design of the small, thin Hitoe® Fold Aria wallet.

Inner hook to hang on the card integrated with the bill holder

It not only serves as a clasp but also prevents cards from falling out.

It is tucked inside to prevent accidental card drops

Clipped with leather. That's all there is to it.

Flat appearance with just a leather clasp. No metal fittings, flaps, or other unnecessary items stick out, so it remains thin and won't get caught in your pocket.
The design prevents the inner hook from coming off when the front and back are reversed. Therefore, there is no need to worry about dropping coins by opening the wrong side up or down.

Minimalist shape with no waste

Minimal and smooth operability

Quick accounting with minimal movements

The wallet can be easily opened and closed with a " ku" bend, which is where the name "Fold" comes from. With this single action, the wallet remains in portrait orientation, and money and cards can all be smoothly inserted and removed.

Bend the wallet in a "w-shaped" motion to open and close it smoothly.
(For right-handed users) The trick is to bend the bottom of the wallet with your left hand in a "crisscross" motion, so that it does not touch the inner hook.

Keep bills in the wallet without folding them.

Just insert bills without folding them. They are highly visible and easy to remove. Since it does not get folded or tri-folded, it is gentle on the receiver and goes smoothly into vending machines and self-checkout machines.
The bill holder is designed to be continuous with the inner hook. The curve of the hook serves as a guide, allowing smooth insertion and removal without snagging.

Smoothly inserts and removes cards without touching the bill holder at all.

Prevents cards from falling out

When the wallet is closed, the inner hook hangs on the card so it will not fall out. Even when the wallet is open, the slip-less design (patent pending ) prevents cards from falling out.
The feeling of slipping a card in and out of the wallet is of high quality and comfortable.

Effects of the slipless design (patent pending)

Temporary cards are held in the bill holder. No problem with opening and closing the wallet.

Occasional cards can be held in the bill holder.

Smooth, non-overflowing coin pocket

The coin pocket is shallow and has no fasteners, hooks, or other metal fittings, so you can quickly remove the coins you need without removing them.
When storing coins, the coin pocket lid serves as a guide for smooth storage.
When the wallet is closed, coins will not overflow. Even when the wallet is open, the coin pocket lid prevents overflow.
There is room for 999 yen (15 coins).

The coin pocket does not overflow while in use.

Design in accordance with the laws of nature

Why is the Golden Ratio so beautiful?
The Golden Ratio 1:1.62 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. (Figure below)
In fact, the Fibonacci sequence is hidden everywhere in nature. Tree branches, the number of petals, sunflower seeds, seashells, typhoons, spiral galaxies. It can also be found in the art of beauty, such as the pyramids, the Parthenon, and the 36 Views of Mount Fuji.
It is not the golden ratio that is important. It is the Fibonacci sequence, in which the proportions from the smallest detail to the whole are deeply related to nature and the providence of life, that results in a harmonious design that resonates with the heart.

Design based on the Fibonacci Sequence

Beautiful details

The precise and delicate stitching, the polished leather edges that reveal the overlapping layers of leather , and the fine lines placed around the edges with a hot iron.
Every detail of Hitoe® Fold Aria, a small, thin wallet, is beautiful.

Beautiful edge treatment

Long and beautiful use

Generally, most problems with wallets are caused by hardware or sewing. However, the Hitoe® Fold, a small thin wallet, uses no hardware and only four stitches.
In addition, the corners, which are prone to damage, are made of layers of outer and inner leather to increase durability. The seam allowance is as small as possible, so the design does not easily lose its shape even in a trouser pocket.

The corners are layered with leather for durability.

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.
