Our manufacturer uses pit-tanned leather for this product. The long, narrow strap of the key chain is made from harness leather. Typically, the leather used for riding harnesses derives from a rugged leather section on the back of a cow. For all its toughness this leather is still pliable after pit tanning and becomes even more beautiful and supple with use. A brass book screw secures the loop. A woven polyester strap holds the keyring – made of brass-plated spring steel – in the short version. Hand-made in Hamburg. The leather is tanned in North Germany.
