Write smoothly, draw flawlessly, erase cleanly and revise repeatedly without damaging your documents or fabric with an unique thermo-sensitive, erasable ink available in a variety of fun colors. The extra durable, bold point tip produces rich, vibrant lines, with a quick drying ink that won't bleed. Marks can be erased off of fabric or wool felt with an iron. If a chalky (white) residue remains, after ironing, simply blot with water to remove. Perfect for marking darts, buttonholes, notches, alterations, and embroidery!
*Do not expose to extreme temperatures (<14?,>140?). If pen is exposed to temperature that reaches 140?, the ink will be colorless when writing. To restore color, cool to at least 14? in freezer and the ink will again write in color.
