Bone colder made by hand of my own design using historical ring and dot patterns. Adapted to historical leather goods, these bone folds are still used today, it can help to turn a leather bag inside, help to wet the shape leather and sting the corners as well as brownish edges. The conical ring and the dot pattern are pierced at the back and then filled with a historical mixture and sanded to create a perfectly flat surface. About 7.75 inches long 1 inch wide.
