"Wrap" your heart, the beauty of Japan

Hospitality that wraps an important business card in one piece of leather

In Japan, there is a culture of carefully wrapping important things such as furoshiki, fukusa, and shugi-bukuro used for gifts.
I designed the business card holder from this traditional Japanese aesthetic sense of "wrapping".
No fasteners such as threads, metal fittings or belts are used. High-quality leather is folded beautifully like origami to wrap important business cards.

In Japan, we treat your business cards with great care.
"TSUTSUMU®", which carefully wraps important business cards, is a business item that conveys Japanese hospitality culture to the other party as well as your own dignity and sensibility .

Solve tsutsumu All solved

An act of caring for the other person

Carefully wrapped things can be thoughtful and considerate in the way they are solved. In the business scene, it is important not to keep the other party waiting.
Since "TSUTSUMU®" has no fasteners, it can be opened quickly and business cards can be taken out smoothly.
The inside is also smooth leather, the business card slides well, and there is no stress.
At first, it is difficult to distinguish the top and bottom, but on the lid side, which you often touch, the wax can be removed quickly, and the more you use it, the easier it is to understand.

Use tsutsumu Despite its small size, it can store 25 regular business cards.

Neat beauty

Logo-free appearance, fine details, sharp and symmetric design.

The center of tsutsumu Simple design

Commitment to Made in TOKYO

High precision is required for the minimal design of SYRINX. For this reason, SYRINX's commitment is carefully realized at domestic workshops with high technical capabilities related to solid pasting, rather than mass production at factories.
In addition, the edge (cross section of leather) is polished, and the edges are finely lined with a heated iron, and attention is paid to every detail without compromise.
From design to manufacturing, we do everything in Tokyo and deliver the world-class Made in TOKYO quality.

For " Aria ", use thin leather "solid paste (entire surface glue)".
With the technique that is said to be the best luxury of leather products, two thinly strained leathers are glued together to make it stronger, lighter and thinner.
It takes a wealth of experience and skill to finish two thin pieces of leather without floating or bending when folded, giving the illusion of one piece.
Since no core material is used, the characteristics of leather vary greatly in units of 0.1 mm. In addition, the combination of leather to be bonded gives a different feeling of tension, from soft texture to strong elasticity.

Specifications are determined by repeating trial and error with various materials and thicknesses.

About aging

The leather used for the outer leather is tannin tanned double shoulder leather with white wax processing, and the white powder is wax called bloom. The more you use it, the more the wax on the surface rubs and penetrates, giving a transparent look.
The interior leather is the same color leather that has not been waxed. With a fine grained surface, it creates a beautiful gradation with the exterior when opened.

The shoulder is also a part that contains a lot of loose scratches, uneven color, blood lines and tigers (wrinkles), and you can enjoy the expression unique to natural leather.
It contains enough oil and wax, so no special maintenance is required.
The surface is delicate and vulnerable, but you don't have to be overly nervous. By picking it up and using it regularly, you will be able to get used to scratches and stains as well as deepening the color and luster.

The cows that are the source of this leather are grazing and bred so that they can grow healthy without stress. This leather has a delicate finish so that you can enjoy the original charm of high-quality leather. Therefore, "living proof (natural mark)" such as wrinkles and scratch marks that originally existed may be engraved. The Natural Mark is a proof of good quality natural leather, and as you use it, it becomes the unique taste of the product.

Rose wound / bloodline


It is a trace of a small scratch or insect bite when bumping or fighting. The more you grow up in an environment closer to nature, the more you grow. Depth, length, and size vary depending on the individual.


It is often found after blood vessels, especially on the floor.



It is a trace of deep wrinkles that are often seen from around the neck to along the spine. Italian leather is popular because it is said that the more tigers there are, the more beautiful it is. The fiber density around the spine is the highest, and there is no problem with strength.

Color unevenness

Color unevenness

Color unevenness may occur due to differences in fiber density. Due to the unevenness of the leather quality, it is unavoidable as long as the leather is a natural material.
Please note that it is the one and only individuality of leather.
