The Duo Marker and Eraser is the answer for truly easy marking and removal on fabric. The special Polyether point has a fine point for no-bleed marks on cotton and cotton blends. Large ink reservoir gives smooth lay down of ink and a longer marking life. To cleanly remove ink lines, lightly guide the chisel point of the Eraser Pen along the line. Do not press down hard. The ink will be removed even after being on the fabric for some time!
