The water-erasable marking pen from Prym is especially useful for tracing markings, which must not be visible, once the patchwork, quilting, sewing or embroidery has been finished. The trick marker is a water-erasable felt-tip pen, available in white or turquoise; it should be stored vertically, with the cap downwards, in order to prevent it drying out. Available in two cartridge thicknesses, it allows you to trace fine or heavy lines without difficulty onto light-coloured and dark fabrics. The Aqua trick marker with extra fine stroke is available only in turquoise. All marking can be removed from the fabric by dabbing with a damp cloth or by using the water pen from Prym. 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.
