Leather strap, perfect to upgrade any bag project. With a length of 130 to 140cm these are perfect for 1 crossbody strap or 2 handles. We carefully selected this leather with a thickness of about 2.2mm. It is sturdy with little to no stretch, but can still be sewn over with most domestic sewing machines (and a leather needle). But if your not sure, our rivets will do the trick!
