COATS&CLARK-Susan Bates Smart-Glo Knitting Needles. SmartGlo knitting needles are made of lightweight plastic that glows in the dark. These needles are warm to the touch and easy on the hands. Because they glow in the dark you will be able to see your stitches in dimly lit places like movie theaters and cars. No batteries required; they are easily recharged in natural or artificial light in just minutes. The knobs feature a no-roll design and the US and metric sizes are clearly printed on the knob. Available in 14in length in all the most popular sizes: each sold separately. Imported.
