This is a leather strop crafted by American Bison Made, who specializes in handmade, long-lasting leather products.
This special leather was produced in the Hermann Oak Leather Tannery. If you're not already in love you should give Bison Made and the Hermann Oak Leather Tannery a quick look on Youtube, but be careful, you might end up being addicted to this brand for the rest of your life.
It is a relatively stiff and thick leather with a nice burgundy-colored design. The inner side of the strop has a canvas lining that's used after shaving to remove any moisture and leftovers from your knife.
A strop is a piece of leather that aligns the edge of a straight razor, and should be used both before and after shaving with it.
