Used a few times for transferring embroidery patterns. I'm selling these to organize my craft supplies. "Clover Clover" ・Tracer Twin (Red) A fine and thick twin-tip tracer ideal for transferring detailed patterns using Chaco paper. The pen shaft is hexagonal, making it easy to hold and preventing rolling. ・Tracer (White) Discontinued product. ※No packaging. There may be some color changes from the time of purchase.
