Tsukineko StazOn Stamp Pads are a solvent-based ink pad designed for decoration on non-porous surfaces such as glass, metal, shrink plastic, cellophane, aluminum foil, leather and acrylic. 
Mild smell, safe to use, and no need to re-ink the pad before each use. Includes 1 pad and a 1/2 ounce bottle of ink to refill your pad.
Porous surfaces such as leather, wood and fabric may not result in fully opaque impressions.
Acid-free and water soluble.
