Herm Sprenger® Stainless Steel Choke Collars
These are training collars that tighten when the dog strains at the leash. They should be used as a sharp reminder, or as a guide, and not with constant, heavy pressure, such as to choke the dog. They are made of exquisite materials and are rust-resistant.
Links are 4.0mm thickness
