“Both knit-in thread and knit-in tape are coated with a reflective material and can be worked into knitting and crochet projects together with the ordinary yarn. This gives the caps, cuffs or wristlets knitted with it a reflector effect. In this way the fancy yarn ensures increased safety in traffic in the dark winter months or during outdoor sports activities. The yarn and the tape with the silvery reflective effect are available in 0.5 mm 50 meters and 1 mm 25 meters thicknesses and can be washed at a temperature of up to 30 degrees.” 100% Polyethylene.
