"Fireline is a pre-waxed, braided cord consisting of gel-spun polyethylene which is known as the strongest fiber, per diameter, ever created. It has an unbelievably high tensile strength and has been recommended in numerous how-to articles on beadworking. The 4 & 6 lb. tests will fit a #12 English beading needle. We highly recommend Fiskars 5 inch Precision Scissors for cutting this thread. Black Satin Fireline is a permanent black color, manufactured with black raw material. It is not a coated or dyed product. No color will come off while using."
FireLine made especially by Berkley for BeadSmith is your trusted Braided Bead Thread. Made in the USA.
