Black German stainless steel will not rust and will perform for the years to come. The links are designed for dogs with shorter hair, the collar is designed to work with nervous dogs, and dogs that are aggressive.
This collar is made of black stainless steel. Black stainless steel is the same composition of iron, chromium, silicon, nickel and carbon that makes up traditional stainless steel. But it has a protective coating of polymer that creates a black matte finish.
