This project began in January 2024 following the Noto Peninsula Earthquake. As the name "Musubu" (meaning "to tie" or "to connect") suggests, we hope to connect people, hearts, and the future while providing support to those affected by the disaster. SYRINX will continue to do what we can, in the ways that we can.
Donation rate: 10% of sales (excluding tax)

Sandwiched in leather. That's all.

A design of ultimate minimalism, simply sandwiching keys between V-shaped leather. (Japan Patent Office Design Registration No. 1623076)
A way to bundle keys like never before

Keys are bundled using a leather cord. Conventional metal rings are bulky and clunky. The "Musubu Key Case" uses the softness of a leather cord to bundle keys compactly. It feels gentle to the touch and allows you to take keys in and out with one hand, even while carrying bags.
Flexible capacity: Hold 1 to 10 keys

Because the length of the leather cord can be adjusted, you can choose the number of keys. It can bundle up to approximately 10 keys.

If you bundle several keys, the case can stand upright, preventing them from scattering on your desk.
How to use
1. Thread

Remove any metal rings and thread the keys directly onto the leather cord.
2. Tie

Loosely pass the leather cord through the three holes, then pull the cord tight to secure it firmly.
3. Cut

Use a utility knife to cut off the excess leather cord.
Notes
- A long leather cord is provided to flexibly accommodate the number of keys.
- The leather cord will stretch slightly and become thinner with use.
- Be careful not to cut the cord too short, as this will make it difficult to swap keys later.
- This product is intended for users who do not change their keys frequently.
- The key hole must be at least 5mm wide to accommodate the leather cord.
- Some car keys or smart keys may not fit depending on their size or the position of the hole.
Ultimate Upcycling of Scrap Material
This small, idea-packed key case was developed to effectively utilize scrap leather left over from larger products, minimizing waste. We only produce it when large scraps are generated; by utilizing leather that would otherwise be discarded, we are able to offer it at a very reasonable price.
Smooth-textured Vacchetta Leather
"Liscio" means smooth in Italian. Made from traditional Vacchetta leather, it is tanned with plant-based tannins and oils, deepening in color and luster the more you use it. The surface is smooth and fine-grained, with natural color variations and natural marks, giving it a sophisticated and tasteful leather character.

Origins
Liscio, Italian for "smooth." Its surface is smooth and fine-grained, with natural color variations and natural marks, giving it a sophisticated and rich leather-like appearance.
Tanning and Manufacturing
"Vacchetta leather" is a traditional Italian leather tanning technique from Tuscany, dating back to the early 9th century. Cowhide is tanned with vegetable tannins extracted from chestnut and mimosa, then slowly infused with oil and finished with dye. The internal oils gradually emerge with use, deepening its color and luster.
LWG (Leather Working Group) environmental certification: Silver rank.
Maintenance
Due to the sufficient oil content, oil treatment is not necessary unless you are concerned about scratches or dryness. For daily care, we recommend wiping with a soft, dry cloth or brushing. For more details, please refer here.
