Cord ends are used for ending threading materials and they enable attaching other findings, such as clasps. Cord ends have a small spike on the back, which protects the inserted material from shifting and unwanted slipping. For better fixation, we recommend using a small amount of glue on the cord end. Cord ends are made of hypoallergenic stainless steel 316L and they meet strict requirements for cadmium, nickel and lead content.
