For a custom look you can choose between three different color hardware options, Nickle, Brass, and Antique Brass. All the hardware on our dog collars are made of 100% Brass. The buckles are a roller style. All collars are solid riveted and stitched for extra hold, with solid one-piece loops, to securely hold even the strongest dog.  Our dog collars are made to last with strength and quality.
