You get five 'Big Eye' needles in this package. The 'Big Eye' is really two very slender needles that are attached together to form a huge eye that is simple to thread with any thread. These are a little longer than 2 inches (5cm) long and are thin enough to pass through the holes in most medium to large pearls, most gemstone beads and almost any glass bead. At the widest point, they measure about 0.6mm. You also get one of our Tri-Tube Storage Vials with the matching lid to keep your needles in when you aren't using them (or use the vial to store other jewelry supplies).
