These non-toxic, non-flammable inks are especially formulated for fabric screen painting, also called silkscreening. Because they are water-based, they offer the advantage of soap and water cleanup without sacrificing any color intensity or durability. Yet, when properly heat-set, the inks become fast and will not wash out. Mix the inks to create an even wider range of colors. This set includes four 4 oz. jars of fabric screen printing inks. The colors included are red, blue, yellow and black.
