Speedball Oil Base Block Printing Inks are waterproof and permanent.
They clean up with kerosene, mineral spirits, or turpentine. Consider the use of non-toxic turpentine substitutes for clean-up. The inks themselves are non-toxic, and conform to ASTM D 4236.
Colors are intermixable. All colors are available in 1.25 oz (37 ml) tubes.
