Tsukineko Memento stamp ink is an acid-free, water-based ink that dries quickly and does not fade. This dye ink produces a sharp, permanent stamp impression on virtually any kind of paper, therewith combining perfectly with watercolours and alcohol markers. The ink does not run when you paint over it with water or alcohol markers. This makes Memento ink a great basic stamping ink for a wide range of wet techniques as well as mixed media projects. The stamp pad is made of a sturdy felt ink pad with a layer of fabric on top. Memento is available in a variety of colours in both small and large stamp pads.
