Benecchi Ultra Fine Thread 12/0 Spool

ULTRAFINE is the finest tying thread currently available. It’s a genuine 12/0 with parallel and crimped microfibers. It may be used safely during construction because of the breakage load (450 grams). This thread is essential for easily tying all small and medium-sized flies; it is not waxed and is crimped (fibre crimping provides an excellent grip).
