Small key case
Musubu® ∞ Key Case - Foschia -

It's just sandwiched between leather.

A minimalist design that is simply sandwiched between V-shaped leather. (Patent Office Design Registration No. 1623076)
A new way to tie your keys

The keys are bound together with a leather cord. Traditionally, keys were made of a series of metal rings, which made them bulky.
The "Tie Key Case" uses soft leather string to tie your keys compactly.
This was made possible by a completely new way of tying, which securely connects the rope with just three holes.
It has a soft feel and allows you to take your keys in and out with one hand while still holding your luggage.
The number of keys can be freely set from 1 to 10.

The length of the leather cord can be adjusted, so you can tie up to 10 keys at most.

You can bundle several keys together and store them upright, so they won't be spread out on your desk.
How to use
1 Pass

If there is a metal ring, remove it and thread the key directly onto the leather strap.
2. Tie

Loosely thread the leather string through the three holes and then tighten it so that it is tied securely and will not come undone.
3. Cut

Cut off the excess leather strap with a utility knife.
Notes
- We provide a long leather cord so that you can flexibly handle the number of keys.
- The leather cord will stretch and thin slightly with use.
- Please note that if you cut the leather cord too short, it will be difficult to change the key.
- It is designed for use where the key is not changed frequently.
- The keyhole must be at least 5mm wide to allow the leather cord to pass through.
- Some car keys and apartment smart keys may not fit depending on the key size and hole position.
The ultimate use of scrap materials
This small key case, packed with ideas, was developed to make effective use of the leftover material left over from cutting out larger products, and to reduce the amount of leather that is discarded as much as possible.We only produce it when we have large leftover material, but because it uses discarded leather, we are able to offer it at a very reasonable price.
Foggy look
Foschia means mist in Italian. It is made of vegetable tanned oil leather with a white wax finish, giving it an appearance like morning mist. The more you use it, the more transparent the appearance becomes.

Origins
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.
Tanning and Manufacturing
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.
Maintenance
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.

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.

It's perfect for locking rotary-type locks. However, pocket keys and touch keys are becoming more common these days, so I'm waiting for a product that supports those!
