Light as air

" Aria " means "Air" in Italian.
It can also mean a lyrical solo song in opera or religious music.
Thin, light, and as invisible as air. Yet beautiful and full of originality. That is the "Aria" series.

The challenge of thinness

The thinness is achieved by using the Hitoe® structure (registered design) which does not stack cards and coins.
- Maximum 5 overlapping pieces of leather, no metal parts , 12mm thickest when stored
(When storing 6 cards, 10 bills, and 10 100 yen coins)
Palm-sized 89mm x 91mm
・Light as air, about 30g
It can hold up to 15 bills, 20 coins, and 6 cards . Even when fully loaded, it remains slim .

The finest unrivaled tailoring

All parts are made by gluing two thin pieces of leather together to make one. This technique is said to be the ultimate luxury in leather products , and it achieves both strength and thinness . It requires a wealth of experience and skilled techniques to create a finish that does not float or sag even when bent, just like a single piece of leather.

Thin details

The edges are made by overlapping the leather and sewing it on the outside. This is to keep it thin. If you fold the leather inside, you can make it smaller, but the leather will overlap and become thicker.
These details are faithful to the ideal of a thin wallet.

While pursuing thinness, we ensure that the leather is thick enough to retain the natural leather texture , such as firmness and elasticity.

Metal fitting-less inner hook

A new idea: use the stored cards as fasteners

We came up with an inner hook (patented) that allows cards to be hung on the wallet instead of on the outside.
The smart leather hook is invisible from the outside , keeping the wallet slim.
This idea made it possible to create the Hitoe® Fold Aria's simple design without any metal fittings .

Not only does it act as a fastener, but it also prevents cards from falling out when you carry it around.

It's just sandwiched between leather.

It has a flat appearance, simply sandwiched between leather. There are no unnecessary protruding parts such as metal fittings or flaps, so it remains slim and doesn't get caught in your pocket.
The inner hook is designed not to come off when the wallet is turned upside down , so there is no need to worry about dropping coins when opening the wallet upside down.

Minimalistic and smooth operation

It can be opened and closed easily by bending it into an " U " shape. With this single action, you can smoothly take out and put in all your coins and cards while keeping the wallet in portrait orientation.

Leave the bills as is without folding them.

Simply insert bills without folding them . They are highly visible and easy to take out. They do not get creases or bends when folded in thirds , so they can be easily inserted into vending machines and self-checkouts.
The bill holder is designed to be continuous with the inner hook. The curve acts as a guide, allowing you to insert and remove bills smoothly without getting caught .

Prevents cards from falling out

When closed, the inner hooks hold the cards so they won't fall out . Even when the wallet is open, the slip-less design (patent pending) makes it difficult for cards to fall out .
The feel of sliding cards in and out is high quality and comfortable.

The extra card can be used as a bill holder . It does not interfere with opening and closing the wallet.

Smooth, non-overflowing coin pocket

The coin pocket is shallow and has no fasteners such as zippers or hooks, so you can quickly take out the coins you need.
When storing, the lid of the coin pocket acts as a guide for smooth storage.
In addition, coins do not spill out when the wallet is closed, and even when it is open, the coin pocket has a lid to prevent spills.
There is still plenty of room even if you put in 999 yen worth (15 sheets).

Design based on the laws of nature

"Why is the golden ratio 1:1.62 beautiful?"
The golden ratio is the ratio that appears when squares with sides that match the Fibonacci sequence (1, 2, 3, 5, 8, 13, 21...) are arranged in a spiral, as shown in the diagram below.

The Fibonacci sequence is hidden throughout nature: in the arrangement of sunflower seeds, the spirals in seashells, the shape of hurricanes, and spiral galaxies.
This sequence can also be found in masterpieces of art, such as the pyramids, the Parthenon, and Thirty-six Views of Mount Fuji.

The golden ratio is not simply a beautiful ratio; its beauty comes from the Fibonacci sequence behind it.

Therefore, the important thing is not to make each part into the golden ratio.
The proportions from the details to the whole form the Fibonacci sequence , which is deeply connected to the laws of nature and life, resulting in a well-balanced design that resonates with the heart.

Beautiful details

Precise and delicate stitching , polished edges that show the overlapping of leather, and thin lines made into the edges with a hot iron.
Hitoe® Fold Aria pursues beauty in every detail .

Long-lasting and beautiful

Generally, most wallet problems are caused by metal parts or stitching. Hitoe® Fold Aria does not use any metal parts and has only four stitches .
In addition, the corners, which are prone to damage, are made more durable by layering the outer and inner leather . The seams are extremely thin, so the bag will not lose its shape even when worn in a trouser pocket .
