Flesh-toned Ink Stone! Our Ink Stones are concentrated, solid ink with sparkly mica powder that is best used for brush work. To use our ink stones, place the stone in a small dish or palette, simply add a couple drops of water or a wet brush to a flat portion of the stone, allowing the stone to hydrate and activate the ink. That's it! Also, you can use the entirety of the stone - no ink goes to waste!
