Rainbow scratch paper is a creative and entertaining art material that offers a unique way to create colorful designs. It typically consists of black-coated paper sheets that reveal vibrant rainbow colors when scratched with a stylus or other sharp tool. This scratch-off technique allows users to draw, write, or create intricate patterns by revealing the vibrant colors underneath the surface layer. It's a fun and mess-free way for kids and adults alike to unleash their creativity and make stunning artworks.
