Musubu® Key Case - Fragola & Bordeaux

Since its establishment, SYRINX has been particular about the leather it chooses. Some leathers have been discontinued for various reasons, but we have kept them with great care. We are offering these leathers as charity products in the hope that they will be made into key cases to support the reconstruction of the disaster-stricken areas.

We would appreciate your support and cooperation.

The photos in the following explanation use different colors of leather. Please refer to the photo at the top of the page for the color of the charity products.

Clipped with leather. Just that.


The minimalist design of the V-shaped leather clasp. (Patent Office Design Registration No. 1623076)

An unprecedented way to bundle keys


The keys are held together by a leather strap. Conventional key cases were bulky with a series of metal rings.
The "Tie Key Case" uses the softness of the leather strap to bind keys in a compact manner.
With its gentle feel, you can insert and remove keys with one hand while holding your luggage.

The number of keys is flexible, from 1 to 10.


The length of the leather strap can be adjusted, so you can carry any number of keys. The maximum number of keys can be bundled together is approximately 10.


If you bundle several keys together, you can place them upright, so they will not spread apart on your desk.

How to use

1. Put it through.


Remove the metal ring, if attached, and put the keys directly through the leather strap.

2 Tie it


Loosely thread the leather strap through the three holes, and then tighten the leather strap to keep it securely tied.

3 Cutting


Cut the excess leather strap with a utility knife.


  • Longer leather strings are supplied to allow for flexibility in the number of keys.
  • The leather strap will become slightly longer and thinner with use.
  • Please note that if the strap is cut too short, it will be difficult to replace the keys.
  • It is intended to be used with keys that are not frequently replaced.
  • The width of the key hole must be at least 5mm in order for the strap to fit through.
  • Car keys, smart keys for apartments, etc. may not fit depending on the size of the key and the position of the hole.
Up to 60mm from the keyhole

The Ultimate Use of Scrap Wood

This small key case full of ideas was developed to reduce the amount of leather to be disposed of as much as possible by effectively utilizing the scraps of material after removing a large product.

Although we only produce this product when large offcuts are generated, we are able to offer it at a very reasonable price because it makes use of discarded leather.

Commitment to Environmental Conservation

Smooth textured vacchetta leather

These two charity products are made of traditional Italian vacchetta leather. The surface is smooth and fine, with natural color irregularities, giving the leather an elegant and tasteful look. The more it is used, the more its color and luster deepens thanks to vegetable tannin and oil.



The manufacturing process and care of the leather is the same as the "Liscio" collection. For details, please see the tab "About Liscio Leather".

∞ Musubu Charity Project ∞

SYRINX has been supported and nurtured by many people through crowdfunding and other means. This project is the result of our employees' desire to give back to the affected areas as soon as possible for their recovery.

Through this project, we sincerely hope for the safety of the people in the affected areas and those who are working hard to rescue and support them, as well as for the earliest possible recovery.

We appreciate your support and cooperation.
