RYU Camouflage Pattern Key Case

Quoted from the brand's homepage:

Made with cow shoulder leather tanned using the traditional Italian Vachetta method, vegetable tannin tanned + dyed finish.
Slim L-shaped zipper key case.
Equipped with a 4-ring key holder inside and 2 card pockets on the side.
It can also store smart keys, and can hold car keys and house keys while maintaining its slim profile.
The unique texture of the leather will further enhance the wearer's charm.
Furthermore, as you use it, the color and luster will dramatically increase, and the surface texture will change, resulting in a more profound and flavorful finish than typical leather surfaces.
