This listing is for 6 oz. of sumi ink, which comes in a container exactly like the one pictured. You’ll want to have a separate vessel on hand (like this glass jar) to transfer the ink into once you receive it! This ink is water-resistant, but not waterproof.
Note that if you’d prefer a smaller size, we offer a 2 oz. bottle.
Sumi inks (KY and KF series) are certified AP non-toxic when used as a painting or drawing material. The AP (Approved Product) Seal identifies art materials that are safe and that are certified in a toxicological evaluation by a medical expert to contain no materials in sufficient quantities to be toxic or injurious to humans, including children, or to cause acute or chronic health problems (when used as recommended).
