Marker Disappears with Blue Iron

Blue Pilot Frixion Ball ballpoint pen with thermo-sensitive ink, ideal for marking light-colored fabrics in sewing, quilting, patchwork, and embroidery. The marking disappears completely when ironed with a hot iron (cotton temperature, no steam) or by friction, making it perfect for temporary sewing lines that need to be erased precisely. Always test on a scrap piece of fabric first, as the ink may leave faint marks on certain fabrics.
