The Detail Black Hybrid Ink Cube by Pinkfresh Studio will give your projects a clear and crisp impression every time you use it! The hybrid formula allows you to use this ink with both watercolor, water-based markers, and alcohol-based markers. You'll love the raised felt pad surface for working with any sized image, and that it's acid free and archival. The size of the cube is just right for fine details and for small thin sentiments. Included in the package is one hybrid ink pad that is made in the USA.
