This Bison leather card case is tanned 100% natural using the same methods that the Native Americans used for thousands of years. Brain tanned Bison leather has its own rich character unlike any other leather. It is thick, yet soft and very durable. Bison leather was used by the Native American's for tipi's, clothing, bags, and horse gear. In addition, it is hand stitched with real elk sinew. Hand tanned buffalo is only available today in very limited quantities. This case is large enough for business cards, credit cards, and cash. Closes with a pewter button. 4.5" x 2.75". Items may vary from what is pictured based on the character of the leather.
