ImpressArt's Stamp Enamel is a water-based, non-toxic, acrylic ink used to darken stamped impressions
1.1 oz (32.5ml) Bottle features small tip for precise application.
Be sure to shake well before use. Just fill your impressions with the stamp enamel, let dry for 10-30 seconds and then wipe off excess with a soft cloth. Easy! Stamp enamel is water resistant but will start to wash out if exposed to soap.
