There’s also a note about the leather: “Our durable leather goods are unlined, featuring the natural suede side of the hide. Because leather is a natural material, slight color and batch variations are normal. Factors like hide age, season, and dye absorption can all affect the final shade, making each piece uniquely yours.”
