The gentle colors of hydrangea
Product Description
Achieved functional beauty
"Perfection is attained not when there is nothing more to add, but when there is nothing more to remove."
These are the words of Antoine de Saint-Exupéry, author of "The Little Prince."
The Hitoe® structure (registered design) prevents items from overlapping, while the inner hook (patented) provides a minimalist, metal-free design and smooth operation. The slipless feature (patent pending) prevents cards from falling out.
"The ultimate form of the Hitoe® Fold series, which has refined both design and usability to their minimalist extremes."
That is Hitoe® Fold Aria.
With its sophisticated design and exquisite craftsmanship, it has been elevated to a breathtakingly perfect functional beauty.

About Ortensia Leather
Soft Hues of the Hydrangea
“Ortensia” means hydrangea in Italian. This leather features beautiful pale tones created through a special white tanning process.
Airy lightness: "Aria"
"Aria" is Italian for "air."
It also refers to a lyrical solo vocal piece in opera or religious music.
Thin, light, and almost imperceptible like air, yet beautiful and full of originality. That's the "Aria" series.

A challenge to thinness
Thinness is achieved with the Hitoe® structure (registered design), which prevents cards and coins from overlapping.
・Maximum 5 layers of leather & no metal hardware
・12mm thickest part when stored
(when storing 6 cards, 10 bills, 10 100-yen coins)
・Palm-sized 89mm x 91mm
・Airy lightness approx. 30g
Can store up to 15 bills, 20 coins, and 6 cards. Even with ample storage, it remains thin.

Finest Double-faced tailoring
All parts are constructed with Double-faced tailoring, where two thin layers of skived leather are bonded together to form a single piece. This technique, considered the ultimate luxury in leather products, achieves both strength and thinness. Creating a finish that is free of lifting or warping when folded, and appears as a single piece of leather, requires extensive experience and skilled craftsmanship.
Thin details
The edges are formed by layering leather and stitching it on the outside. This is a commitment to "thinness." While folding the leather back and tucking it inwards could reduce the size, it would result in overlapping leather and increased thickness.
These details are faithful to the ideal of a thin wallet.
While pursuing thinness, we ensure the leather has ample thickness, valuing the leathery texture with its firmness and resilience.
Metal-free inner hook
A new idea: using the stored card as a fastener
We developed an inner hook (patented) that attaches to the card, not the outside of the wallet.
The wallet remains thin, with a smart leather hook that is invisible from the outside.
This idea made the metal-free, minimalist design of the Hitoe® Fold Aria possible.
In addition to serving as a fastener, it also prevents cards from falling out when carried.
It just clamps with leather. That's all.
Its flat exterior simply clasps with leather. With no protruding metal fittings or flaps, it remains thin and won't snag in your pocket.
The design ensures that the inner hook won't come off if the wallet is inverted. Therefore, there's no need to worry about opening it upside down and dropping coins.
Minimalist and smooth operability
Quick checkout with minimal movement
It can be easily opened and closed with a "V-shape" bending motion, which is where "Fold" gets its name. With this one action, the wallet remains upright, and you can smoothly insert and remove all currency and cards.
Bills remain unfolded
Simply insert bills unfolded. They are highly visible and easy to retrieve. Since there are no creases or folds from tri-folding, they are gentle on the recipient and smoothly fit into vending machines and self-checkout registers.
The bill holder is designed to flow continuously from the inner hook. Its curve acts as a guide, allowing for smooth insertion and removal without snagging.
Prevents cards from falling out
When closed, the inner hook secures the cards, preventing them from falling out. Even when the wallet is open, the slipless feature (patent pending) helps prevent cards from dropping.
The smooth sensation of sliding cards in and out is pleasant and effortless.
Temporary cards can be placed in the bill holder. This does not interfere with the opening and closing of the wallet.
Smooth and spill-proof coin pocket
The coin pocket is shallow and has no metal fittings like zippers or snaps, allowing you to quickly and directly retrieve the necessary coins.
When storing coins, the lid of the coin pocket acts as a guide for smooth insertion.
Furthermore, coins won't spill out when the wallet is closed. Even when open, the coin pocket lid helps prevent spilling.
There's still plenty of room even with 999 yen (15 coins) inside.
Design in harmony with nature's principles
"Why is the golden ratio 1:1.62 beautiful?"
The golden ratio, as shown in the diagram below, is the ratio that appears when squares with sides corresponding to the Fibonacci sequence (1, 2, 3, 5, 8, 13, 21...) are arranged in a spiral.
This Fibonacci sequence is hidden everywhere in nature. The arrangement of sunflower seeds, the spiral of seashells, the shape of typhoons, spiral galaxies, and more.
Furthermore, this sequence can be found in masterpieces of art that have perfected beauty, such as the pyramids, the Parthenon, and the Thirty-Six Views of Mount Fuji.
The golden ratio is not merely beautiful in itself; its beauty is generated by the underlying Fibonacci sequence.
Therefore, it's not about making each part conform to the golden ratio.
A harmonious design that resonates with the heart is achieved when the proportions from the details to the overall structure follow the Fibonacci sequence, which is deeply connected to the principles of nature and life.
Beautiful details
Precise and delicate stitching, polished leather edges that reveal the overlapping leather, and fine lines impressed along the edges with a heated iron.
The Hitoe® Fold Aria pursues beauty down to the smallest detail.
Durable and beautiful for long-term use
Generally, most wallet problems are caused by metal fittings or stitching. However, the Hitoe® Fold uses no metal fittings whatsoever and only four stitches.
Furthermore, the vulnerable corners are reinforced with overlapping outer and inner leather to enhance durability. The seam allowance is minimized, and the design is resistant to losing its shape even in trouser pockets.
| Compact Yet Global
Surprisingly, many currencies around the world are larger than Japan’s ¥10,000 bill or ¥500 coin.
This wallet accommodates most of them, making it comfortable to use even when traveling abroad.
Origins
Ortensia, meaning "hydrangea" in Italian, is characterized by its beautiful pale tones.
Tanning and Manufacturing
Single butts (back to hip area) from Nordic cattle are used. After white tanning, the leather is dyed with aniline dye and then finished with a pigment spray. It is resistant to scratches and dirt, repels water, and hardly ages, so it can maintain its original appearance for a long time. The single butt is the densest and finest-grained part of the hide, providing a uniform and beautiful grain when embossed. LWG (Leather Working Group) Gold certified.
Maintenance
While this leather is resistant to scratches, dirt, and water, if it gets wet, wipe it off immediately and regularly remove dust from the surface with a soft cloth. For more details, please refer to here.

Q. It's not opening/closing smoothly. Are there any tips?
To open and close the wallet smoothly, follow these steps:
【To open】Bend the boundary between the coin pocket and card pocket into a "V" shape, and the inner hook will naturally disengage. There is no need to touch the inner hook directly.
【To close】While gently pressing the top, bend it into a "V" shape using the same method, and the inner hook will naturally catch on the cards.
Q. The wallet gets distorted when closed.
This is because the inner hook is hooked to the outside of the wallet. Please make sure it only hooks to the cards stored inside.

Q. Cards are difficult to remove and feel too tight.
To prevent the card pockets from becoming too loose, they are designed to be a bit snug, and may feel tight at first. Over time, they will gradually adapt to your usage and become easier to remove.
If it feels too tight initially, try inserting and removing one fewer card a few times to break in the leather before regular use.
Q. Will the cards fall out?
When the wallet is closed, the inner hook engages with the cards, preventing them from falling out.
Even when open, the cards are unlikely to fall out due to the anti-slip treatment applied.
The Hitoe® Fold Aria and Hitoe® Fold Less, with their slipless design (patent pending), are even more resistant to cards falling out.
Please note that if the wallet is laid horizontally, the anti-slip effect will be reduced as shown in the video.
Q. Will coins spill out?
The wallet has a lid that prevents coins from spilling, so coins will not spill out during normal use. As the leather breaks in, it will become even more stable.
Please note that this wallet has a vertical design, so if you open it horizontally like a typical bi-fold wallet, coins are more likely to spill out.
Q. The sound of coins bothers me.
When putting the wallet in your pocket, storing it so that the coin pocket is vertical will reduce the sound of coins. It also makes it easier for coins to align automatically.
Q. If I open it from the wrong side, will coins spill out?
Rest assured, if you turn the wallet inside out, the inner hook will not disengage and the wallet will not open.
You can identify the front side as follows (for right-handed users):
- No stitching on the right side
- The right side is where more of the cards are visible
Q. Which should I choose, right-handed or left-handed?
Please choose based on the hand you use to handle money and cards.
Q. Is it okay to stack cards with magnetic stripes?
Modern magnetic stripes have strong magnetic resistance, so stacking them is not an issue. Also, it does not affect IC chips.
However, older magnetic cards may have weaker magnetism, so to be safe, we recommend storing them with the magnetic stripes facing different directions to prevent them from overlapping.
