Magic Paper™
Magic Paper™ is a high performance practice, play and doodling cloth. Magic Paper works with a clean brush and clean water. Magic Paper changes color to black when it becomes wet. Once wetted, Magic Paper dries after about 5 minutes. Once dry, Magic Paper can be used again and again for up to many years of typical use.
