This 3-pack is packaged in a rigid chipboard mailer for extra protection. Collapsible Eye Needles are flexible and are particularly nice for stringing beads that have very small holes. Extra-spring wire is kink-resistant and has a specially designed eye that automatically collapses and instantly reshapes when it is pulled through the bead. The large eye is easy to thread and accommodates many sizes of cord. 2 1/2” needles are great for seed bead projects.
