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. Most beads will not cut this product. It does not stretch, it knots easily, and will pass through a #12 beading needle. Similar to size A or B Nymo. This is the fiber to use for all stringing which requires extra strength or multiple passes, but involves beads with small holes.
