This 3mm sterling silver crimp cover is great for camouflaging crimps while adding a touch of brilliant sterling silver luster to jewelry designs. It will cover crimps that are up to 2x2mm in size. It will hide your crimp tube and make it look like another bead on the strand, creating a professional finishing touch. It will also prevent snagging in your jewelry designs. Crimp covers are open on one side allowing them to slip over the crimp tube and can be closed over a crimp tube with chain or flat nose pliers.
