This filament is incredibly strong even though it is very thin. The smooth thin filament allows for multiple passes through seed beads or sewing on cabochons with extra strength without the bulk of extra thread. The filament can even be split into an ultra-fine fiber for designs that require strength without extra bulk. It is so strong it is woven into a fabric used to make bulletproof vests.Use fisherman-type knots with this material as overhand knots weaken the strength of the thread. 0.2mm 7# test, 0.15mm 6# test
