Griffin High Performance bead cord is a blend of different polyethylene fibers (not nylon). That is one of the reasons, why it is only available in the color white! GRIFFIN High Performance bead cord is a blend of high-tech fibers (with a special dense molecular structure) and silk. Silk makes this bead cord smoother, which is a perfect compromise between strongness and smoothness.The cord is sold on 2 meter cards.
