"keu" is a leather brand that expresses the beauty of chance and decay through "rust-aged leather," which is made by applying a unique rust treatment to genuine leather.

"keu" is created by waji, a group of artisans who develop leather wallets and other leather goods. The material used, "rust-aged leather," is made by spraying metal powders such as brass, copper, and iron onto the surface of the leather to induce rust. The rust patterns on the surface of the genuine leather are unique, each one different, and possess a subtle yet striking individuality.

"keu" leather goods utilize a seamless pattern with minimal stitching to maximize the unique characteristics of the rust-aged leather. Furthermore, intricate thinning (partial adjustment of leather thickness) is applied to achieve a simple silhouette. The brand logo is intentionally omitted, resulting in a minimalist design that highlights the charm of the rust-aged leather.

Aiming to create "crafts for everyday use," the leather items of "keu," crafted with the experience and sensibility of leather artisans, exude a unique and rare presence, imbued with a Japanese sense of "wabi-sabi" (a Japanese aesthetic of accepting the impermanence of things).
