LEATHER KEY SHACKLE SS23 Designed for durabilityDetails: Crafted in Japan from cow leather and stainless steel, it combines a solid metal shackle structure with a soft leather wrap, creating a refined balance between industrial function and tactile warmth. Designed for everyday carry, it securely holds keys while also working as a subtle accessory detail. Over time, the leather develops a rich patina, deepening in tone and character with use, making each piece feel increasingly personal. 100%
