Cosmic Shimmer Opal Polish - Red Pearl contains mica pigment which will bring extra detail to designs and the pot has its own incorporated delivery system making it easy to apply to a variety of surfaces. This polish can be used for stamping, just cover your stamp with the polish, then spray water on sponge, put back in pot and wipe off lid - you are then all ready to start next time. The mica gives the polish an interferance factor so that when put onto black card you will create a different colour than if stamped onto white card!
