Hero Arts Hero Hues Warm Pigment 4-Cube PackA set of four 1. 25"x 1. 25" ink cubes in Rose Quartz, Ruby, Tiger's Eye and Citrine. Pigment inks are crisp and opaque, sitting on top of paper for a vibrant intensity, making them ideal for use with embossing powders as they dry a little slower than our other inks. Use a heat tool to speed up drying time. Clear lids highlight the beauty of the ink colors, which appear true to color in the pad. Acid free, archival and fade resistant.
