Marker and eraser. A practical kit designed for precise, temporary marking of contact points, lines, or cuts on fabrics. It includes a double-sided pen with pink and violet ink that gradually disappears — pink within approximately 24 hours and violet within 48 hours. The fading time depends on the type of material, ambient temperature, humidity, and air circulation. Marks can also be removed instantly using water or the included special eraser, which is non-toxic and works by simply tracing over the ink twice. Before use, it is recommended to test the marker on a fabric sample and leave it for 48 hours to avoid unwanted reactions. This set is ideal for tailors, embroiderers and designers.
