Higgins Non-Waterproof Black Ink is perfect for use with brushes and dip pens on a range of surfaces from board to film. This ink will erase from film easily with just water. Its intense, carbon-black formula is capable of producing a full scale of beautiful, fade-proof grays when diluted with varying amounts of water. Higgins Non-Waterproof Ink will reliably not chip, peel, feather or smear, making it an ideal artists painting and drawing medium. Available in a 1 oz. dropper bottle.
