TRADITION MEETS MODERN LOOK High-quality dog collars made of blackened stainless steel All collars in the standard range made of stainless steel form the basis for this quality. During a galvanic process, the surface is blackened and finally polished. Since it is not a hard coating, the permanent friction of the fur on the metal can create an attractive antique look. We recommend our standard range of stainless steel with polished surfaces or CUROGAN for dogs with a tendency to discolor fur. Look out for our metal tag with the red dot and the HS-GERMANY INOX stamp on all rings and swivels when buying a black stainless steel product.16-inch Stainless steel black prong collar.
