TSUKINEKO-Opalite Inks. Opalite interference ink creates a multi-dimensional optical illusion: the color of ink is reflected differently depending on the color; material and texture of the surface it is applied to. All wavelengths of light are absorbed except the specific wavelength that is being reflected back to the viewer; which allows the viewer to see a vibrant; dazzling interference color. Archival and acid free pigment ink ideal for use on wood; dark paper; leather and much more. Imported.
