Bookmark Disappears with Black Iron

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