Pet Care, Toys, Supplies and Products for Animals Design At Leash Pet Accessory Set by Lance Francisco At Leash is a collar and leash set for pets. The collar and the leash are made of TPU-coated webbing, chosen for durability, flexibility and water resistance. Both parts are 3.8 centimeters wide, and the wide form spreads pressure evenly for pet comfort. Reinforced holes of 9 millimeters allow charms to be attached, so each set can be personalized. A snap buckle allows quick fastening and release. The handle can be adjusted for carrying in the hand, at the waist or across the body.
