Acid-free coloured stamp ink of good quality suitable for various surfaces, including paper, cardboard, carton, papier-mâché and so on. Can also be used on fabrics, which after ironing are resistant to light hand washing. The stamp pad is easy to use. Simply dab the stamp ink in an even layer directly onto the stamp. The amount of ink on the stamp determines the intensity of the print - the more ink you apply, the clearer the print. Clean the stamps in lukewarm water after use.
