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. Turquoise. AP Seal, non-toxic.
