Two pens in one! The blue end is Mark-B-Gone ink which removes with a damp cloth. The purple end is disappearing ink: air & water soluble marks fade away on their own.

Use the Dritz Dual-Purpose Marking Pen to transfer pattern markings, needlecraft & quilting designs. May also be used for some alteration markings. Test first to be sure of fadability/washability. For best results, use on washable fabric. Not recommended for dry clean only fabrics.
