The Tsutsumu® Card Case has won seven international design awards and can be said to be the origin of SYRINX's leather items.
This masterpiece has become even more beautiful, refined, and smaller, weighing just 17g.
You can choose between right-handed and left-handed versions.

"Aria" is an Italian word meaning "air," and also refers to a lyrical solo song in opera or religious music.
The Aria series is thin, light, and so airy that you forget it's even there. Yet it is beautiful and full of originality.
“Foschia” means “fog” in Italian. This leather is characterized by its white, misty waxed finish, reminiscent of a morning fog.
As you use it, the wax gradually absorbs into the leather, revealing a clear and elegant sheen.
All parts are made using the Double-faced technique , which involves gluing two thin pieces of leather together to create a single piece. This technique is said to be the ultimate luxury in leather products , achieving both strength and thinness . It requires extensive experience and skilled techniques to create a finish that remains firm and supple even when bent, just like a single piece of leather.

In Japan, there is a culture of carefully wrapping important items, such as furoshiki, fukusa, and noshi bags used for gifts.
The business card holder was designed based on this traditional Japanese aesthetic of "wrapping."
No fasteners such as threads, metal fittings, or belts are used. High-quality leather is simply folded beautifully like origami paper to wrap your important business cards.
In Japan, business cards received are treated with respect.
"Tsutsumu®" carefully wraps your important business cards, and is a business item that conveys not only your own dignity and sensibility, but also the Japanese culture of hospitality to the other party.

When you unwrap something carefully, the act of unwrapping it also shows consideration and thoughtfulness. In business situations, it is important not to keep the other person waiting.
"Tsutsumu®" has no fasteners, so it opens quickly and you can easily take out your business cards.
The interior is also made of smooth leather, so business cards slide easily and without any stress.
At first it may be difficult to tell the top from the bottom, but the wax on the lid, which you touch most often, will come off quickly, and the more you use it, the easier it will be to tell the difference.

A logo-free exterior, exquisite details, and a sharp, symmetrical design.
Its understated and refined beauty exudes elegance.


Foschia, meaning "fog" in Italian, is characterized by its white wax-covered appearance, reminiscent of morning mist. As it is used, the wax permeates the leather, revealing a translucent finish.
Made from bovine shoulder leather sourced from Northern Europe. After vegetable tanning, the surface is lightly buffed (polished) and then coated with white wax.
Natural marks may also be visible.
LWG (Leather Working Group) Environmental Certification Gold Rank.
As the wax gradually permeates, an elegant and natural sheen develops. Oil care is not required unless scratches or dryness are a concern. For more details, please refer to here.
Light colors have a delicate surface and are prone to visible stains and scratches, requiring careful handling.

※ Due to monitor settings, and differences in dye absorption depending on the condition and part of the raw hide, and the season, there may be slight variations between the displayed color and the actual color.
About Scuff Marks
Where the white wax is rubbed, the natural color of the leather appears, making it look darker and temporarily like fine scratches. As the wax permeates during regular use, the initial marks will gradually fade, and the leather will be covered with a translucent sheen.
During production and packpatina, minor scuffs and pressure marks may occur, resulting in individual variations in how the wax remains initially. Rest assured, the leather itself is not damaged, and these variations will become uniform as patina progresses.
About Wrinkles
Due to the wax, Foschia leather tends to wrinkle easily on the surface when bent sharply. As it is used, these wrinkles will be covered with a sheen, and the texture will gradually settle.
The video below shows an example where the entire leather was intentionally wrinkled and then used for about a month in a back pocket of trousers. The luster increases, and the wrinkle patterns develop a subdued character.
