Excellent quality, highly pigmented, water-based ink is a great value for schools. Inks completely intermix to extend the range of colors. Color goes on smoothly and evenly and dries to a satin finish. Terrific for block printing projects using linoleum, wood block, polyfoam or flexible vinyl plates. Easy to cleanup with soap and water. 16 oz. jar. Metallic silver. AP Seal, non-toxic.
