About Monocromo Leather
Refined Monochrome
“Monocromo” means “monochrome” in Italian.
The outer leather features a textured white grain, while the interior is finished in smooth black—creating a striking two-tone contrast.
technology
Innovative ideas and the exquisite skills of craftsmen
| Patented technology inner hook
This patented technology uses the card itself as the fastener, a completely new concept. It eliminates the need for any metal fittings, resulting in a thin, flat design. Since the wallet won't open if the card is opened incorrectly, there's no worry of coins spilling out.
| Extremely thin Hitoe® structure
The "Hitoe® structure" allows you to arrange cards, coins, and banknotes without overlapping them, achieving an astonishingly thin design without compromising storage capacity. The overlapping of leather is also limited to a maximum of five layers.
Even with 10 banknotes, 15 coins, and 6 cards stored inside, the thickness is only 12mm * .
* Thickest part excluding the coin pocket
| The finest, unparalleled tailoring
"Musou-jitate" is a technique that uses two pieces of leather bonded together to create a smooth finish that resembles a single piece of leather. This technique, which combines durability and elegance, embodies the exquisite and skilled craftsmanship of artisans.
| Slip-free design (patent pending)
Inserting and removing cards is always smooth, yet they are less likely to accidentally fall out.
design
The harmony of beauty and function guided by the laws of nature.
| Ultimate Functional Beauty
"Perfection is the state in which it cannot be further refined." — Antoine de Saint-Exupéry <br> Through sophisticated design and exquisite craftsmanship, we have pursued thinness, lightness, and functional beauty.
| The laws of beauty created by nature
The beautiful harmony of the natural world, as depicted by the Fibonacci sequence, has been incorporated into the proportions of this wallet.
Each time you pick it up, you'll feel its harmonious beauty resonate deeply within your heart.
| Aesthetics of detail
Delicate stitching, carefully polished leather edges, and thin lines along the rim.
The aesthetic sensibility evident in the details gives this wallet a profound presence.
| Details for thinness
The leather pieces were sewn together on the outside, minimizing overlap.
These details are faithful to the ideal we are striving for.
| Beauty achieved solely through leather
There are no metal fittings or flaps. It's a simple design that just uses leather to hold everything in place. Because there's nothing extra to it, it won't snag on anything, and you can carry it smartly wherever you go.
Durable and beautiful for a long time
No metal parts were used, and the stitching was placed in locations that are less likely to wear out.
The easily damaged corners are reinforced with extra layers of leather to improve durability.
Furthermore, the seams are extremely thin, making it less likely to lose its shape even when placed in a pocket.
Ease of use
Make your daily routines simpler.
One-action comfort
Simply bend your wallet into a "V" shape. You can instantly take out both banknotes and cards.
Paying at the register is smooth and smart.
| Without folding the banknotes, as they are.
Banknotes can be stored as they are. They won't get creased, and you can use vending machines and self-checkout machines smoothly.
| Temporary cards are also beautiful
The bill holder section can store cards you don't use often. It doesn't affect the opening and closing of the wallet, and it's just as easy to take them out.
| Easy-to-access, spill-proof coin pocket
The coin pocket features a simple design without zippers or snaps. Its shallow pocket and short flap make it easy to access and prevent coins from spilling out. It has a storage capacity of 15 coins (999 yen) or more.
| 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.
| Comfortable pockets
It's so thin you'll forget you even have it in your pocket.
Bring minimalist choices into your daily life that will lighten your spirit as well.
Origins
Monocromo means "monochrome" in Italian.
The contrast between the two colors, the grainy white outer leather and the smooth black inner leather, is a distinctive feature.
Tanning and Manufacturing
The leather is made from a single butt (back to hip) of an adult Scandinavian cow. After white-tanning, the leather is dyed with aniline dyes and finished with a spray of pigments. The leather is scratch and stain resistant, water repellent, and hardly ages, so it retains its original look for a long time.
Single butt has the densest fibers and the finest texture, which gives a uniform and beautiful grain when it is grained.
Maintenance
The leather is resistant to scratches, stains, and water. When wet, wipe it off immediately, and periodically remove dust from the surface with a soft cloth.

Q. I can't open and close it smoothly. Is there any trick to it?
To open and close your wallet smoothly, follow the steps below.
[When opening] Bend the border between the coin pocket and the card pocket into a "U" shape and the inner hook will come off naturally. There is no need to touch the inner hook directly.
[When closing] While lightly pressing the top, bend it into an "U" shape in the same way, and the inner hook will naturally catch on the card.
Q. My wallet becomes distorted when closed.
This is because the inner hook is attached to the outside of the wallet, so make sure to only attach it to cards that you store inside.

Q. It's difficult to remove cards and it feels cramped
The card pockets are intentionally designed to be a little tight so that they do not become too loose, so they may feel cramped at first. However, over time, they will become more snug and easier to access.
If the bag is too tight at first, try using one less layer and taking it in and out several times to allow the leather to become accustomed to the bag before using it again.
Q: Will the cards fall out?
When the wallet is closed, the inner hooks catch the cards so they won't fall out.
The case has an anti-slip coating so cards are less likely to fall out even when open.
In particular, the slip-less design (patent pending) of the Hitoe® Fold Aria and Hitoe® Fold Less makes them even less likely to fall.
Please note that the anti-slip properties will be less effective if the wallet is laid horizontally.
Q. Will the coins spill?
The wallet has a coin-proof lid that will not spill out with normal use. As the leather breaks in, it becomes even more stable.
Please note that because this wallet has a vertical design, coins are likely to spill out if opened horizontally like a typical bi-fold wallet.
Q. I'm bothered by the sound of coins.
When you put your wallet in your pocket, if you store it with the coin pocket vertically, the coins will not make any noise and will be easier to line up automatically.
Q. Should I choose right-handed or left-handed?
If you use your right hand to insert and remove cards or coins, select right-handed. If you use your left hand, select left-handed.
Q. Will the coins spill out if I open it upside down?
Don't worry, if you turn the wallet inside out, the inner hook will not come off and the wallet will not open.
The surfaces can be identified as follows (for right-handed users):
- No stitching on the right side
- The right side is the side where the card looks wider
Q. Can the magnetic stripes of cards be stacked?
Modern magnetic stripes are highly resistant to magnetism and can be stacked without any problems. Also, stacking IC chips has no effect.
However, the magnetic properties of old magnetic cards, such as bank cards, may have weakened, so as a precaution we recommend storing them so that the magnetic stripes are not touching each other.
