Mustad's durable split rings are made of stainless steel for maximum durability and long life. The design provides high breaking strength while the rings retain their shape under heavy loads. They are easy to fit and are ideal for wobblers, spoons, jigs and other artificial lures where secure hook attachment is essential. Thanks to the stainless steel material, they work equally well in saltwater and freshwater. Available in several sizes for different types of fishing and lures.
