Crimp beads and covers are ending components which are used for making jewellery from nylon tigertails. With their help, you can create a loop for attaching a clasp. We recommend applying a wire guardian to the loop, which will protect the beading wire from unwanted deformation and wear. Crimp beads, wire guardians and crimp bead covers are made of hypoallergenic stainless steel 316L which meets strict requirements for cadmium, nickel and lead content.
