SemperFli Classic Waxed Threads (3/0 to 18/0, many colors)

Using similar techniques as with Nano Silk SemperFli extruded thin Polyester strands which were then slightly twisted and had a light amount of wax added to them. The amount of wax added has been specifically applied after consultations with top Professional Fly Tyers. With the lightly twisted strands this allows the thread to both lay flat and split easier than other threads on the market. Having reviewed the market offerings we also added 12/0 to the range and included Fluorescent colors along with the traditional colours desired. 6/0, 8/0,12/0, and 18/0 all have 240 yds. per spool. 3/0 has 120 yds. per spool.  Breaking Strains: 3/0 - 1114gm / 39.33 oz 6/0 - 938gm / 33.01oz 8/0 - 754gm / 26.6oz 12/0 - 489gm / 17.25oz Other information: Large spools representing great value Lays flat on your hook Wax quantity optimized for fly tying to avoid leaving wax in the bobbin.
