Our Biothane dog Collar is made from top quality Super heavy BioThane. This Biothane is a polyester webbing inside with a TPU coating outside, making it more durable, cleanable, stronger, waterproof, flexible and easier to maintain than leather or fabric. Do not absorb nasty odours or stains, and are chew-proof. Our dog collars are padded with fur for extra comfort. The decorative Stainless Steel hardware and handmade finish make the product look different from other similar products.
