Pinata Colors are beautiful, highly saturated, acid-free, transparent ink colors that make up the signature line of artist Susan Pickering Rothamel. They are alcohol-based, indelible and moisture-resistant when dry. That means you can work freely on almost any clean, oil-free surface including glass, plastic, metal foil, metal, leather, paper and vinyl. Highly versatile, Pinata Colors can be used in a variety of applications such as rubber stamping, fine art and scrapbooking. Also use them for faux finishing techniques, graphic and airbrush applications, and wood and leather staining. They can be mixed or blended. Apply with a stamp, pen, brush or airbrush. In 1/2 oz. squeeze tubes.
