A thin bi-fold wallet that doesn't add bulk to your pocket.
SOPO is a brand based on the concept of creating products that will be comfortable for the person who owns them and will be loved by generations as ``future classics.'' By combining the finest materials with modern, timeless designs and craftsmanship, we create unique items that add color to your everyday life. This bi-fold wallet has a thin design and is designed to be fastened with a snap button to prevent it from flapping open. The leather used is kip leather, which has a natural texture and is made from Dutch raw hides tanned with vegetable tannins at a long-established tanner in Japan. The zipper is made by Riri, which is highly durable. Adds a vintage-like atmosphere.
