Fireline is a pre-waxed, braided cord consisting of gel-spun polyetholine which is known as the strongest fiber, per diameter, ever created. The 4 and 6 lb. tests will fit a #12 beading needle.
Break strength = 6lb, average diameter .006 (.15mm) 50 yard spool.
Made in the USA
I actually tie a knot at my needle so I don't have to think about rethreading while I work. The thread is fine enough to pass right through the bead even with the knot. I work with 8ft lengths in many of my pieces and have no problem handling this thread. Good stuff.
