Crafted from sustainable leather sourced from responsible tanneries, this piece is naturally tanned using pigments derived from tree bark, chestnut fibers, and other found materials. This method preserves the leather’s integrity and allows it to develop a rich patina over time. Each keychain is designed and created in California.

Because the leather is tanned by hand, every keychain features unique color variations, grain differences, and natural markings, ensuring each Casupo accessory is truly one of a kind.
