Rasco Split Rings are super strong - don't let the bargain price fool you. Made from high quality stainless steel, these split rings are made right here in America and are a very popular choice for attaching hooks to lures. These are used on several big brands of lures including Super Strike. Hab's Lures also used these for many years. Rasco or Rosco? They are individual companies. Both make split rings! Both are good quality.
