Prym Trick Marker Pen Self-Erasing Medium:
The self-erasing marking pen from Prym is especially suitable for tracing markings required to disappear once the sewing, quilting or embroidery has been finished. This violet water-erasable felt-tip pen, should be stored with the cartridge pointing downwards, to ensure a lasting flow of ink and to protect it from drying out. Depending on the characteristics of the fabric, the markings disappear without trace spontaneously and as if by magic. Important: Before using the marking pen, use it to mark a test piece of fabric and then test the removal of the marks from that piece of fabric.
