Fireline beading thread has all the benefits of multiple kinds of stringing material at once. It's strong like wire, but supple like thread; it's soft like silk, but resistant to stretching like wire. That's because Fireline thread is a braided polyethylene fiber that comes pre-waxed. When creating projects that require multiple passes through a single bead, Fireline is better than any other type of beading or craft thread.
Berkley Fireline is a gel-spun polyethylene that is braided then thermally fused thread for a smooth finish. The technology used to produce Fireline allows it to be ultra-thin yet very strong. Most beads will not cut Fireline. It works better than fine beading threads due to it's extra strength. It is UV protected to withstand sunlight. The thread is pre-waxed so resists tangles. Fireline is also very stretch resistant.
