The Tuscany leather is the top layer of the collars and leashes. It is a marine grade upholstery leather. That means it is designed to be color fast and sun fade resistent and it also has an anti microbial additive that will help reduce mold and bacteria growth in the leather. The lining is a soft pebble grained leather, we chose this leather for it's strength and softness. When combined with the Tuscany leather together they make what we consider to be one of the best collar and leash lines made today. All metal components are in high quality 316L Stainless Steele to guarantee hold. Leash is 6' long and is embossed with LOVE GOD, LOVE PEOPLE, LOVE DOGS.
