Editorial Review This super strong, flexible, pre-waxed braided beading thread is made from gel-spun polyethylene, one of the strongest fiber cords per diameter ever created. Beadworkers and beadstringers will find that this product feels and works better than the finest bead thread, yet is as strong as jewelry wire. Most beads will not cut this product. It does not stretch and knots easily. Color: Smoke Gray Measurements: 0.006" (.12mm) thick with a 6 pound test weight. We recommend using #12 English beading needles with this size. Quantity: 15 yard (13.7 meter) spool.
