• Semi-opaque embossing crystals• Iridescent shimmering colour• 100ml These ultra thick embossing crystals can be used over a clear ink as well as coloured. The colour of the ink used underneath the embossing crystals will subtly affect the end colour. The crystals are larger than those in a standard embossing powder so if used with a stamp and ink pad, it is recommended that they are heat set from underneath.
