You can ensure your stamped designs stand out even more. This black stamp enamel from ImpressArt is meant to be applied over a metal stamp design. Simply shake the bottle before use, apply the enamel, wait 10-30 seconds, and then gently wipe away the excess with a soft cloth. The enamel will remain in the recesses of your stamped design, creating a more pronounced look. You'll love the professional feel it adds to your projects. Here are further tips for using this product: Before wiping excess stamp enamel, blot it until you see the outline of the impression. The larger the surface area of the impressions, the longer the stamp enamel will need to dry. For wider impressions, allow thirty seconds. Stamp enamel is water resistant, but will start to wash out if exposed to soap. We recommend wiping away any fingerprints or residue before applying the stamp enamel, as it is less likely to adhere to an oily surface.
