The collar is made with 1" wide black nylon webbing with a satin ribbon covering with heavy duty nickel-plated metal hardware and a contoured plastic buckle.  

The collar can also be made in martingale style with or without a buckle.  Martingale collars have an extra loop which a leash attaches to, which allows the collar to tighten a certain amount, preventing the dog from slipping out of it.
