Kirarina WiNK is a multi-purpose pen that is compatible with a variety of surfaces including paper, photos, plastic and glass. The metallic ink allows you to add touches of color on dark surfaces, and all 16 colors contain specks of glass.
For best results when working on absorbent surfaces, slow down, so the paper has time to absorb the ink. Once opened, Kirarina WiNK should be kept stored horizontally to keep the glitter evenly distributed. If you are having issues with ink flow, shake thoroughly and pump the tip.
