This is a 1000m (approximately 1093 yards) glow in the dark thread.
Thread filament is 40 weight (120D/2) and made from nylon.
This is part of the range of our own brand of embroidery threads. It is a high-quality thread with a low breakage rate. Please note that in order to glow, the thread needs to first be exposed to light before darkness. Stronger lights before darkness will help give a stronger and longer glowing effect.
