These specialty inks are perfect for making beautiful fish prints on any kind of paper. Unlike many other fish printing inks or paints, these wash off easily with soap and water. Available in a rainbow of colors, you can also mix colors to make your own shades and variations. Each 37 cc tube will ink about 40 nine-inch fish. To expand design options, we also carry ink extender (increases transparency) and ink retarder (slows drying time).
