Washable ink is a type of ink designed to be easily removed from surfaces, such as skin or fabric, using water. It is commonly used in products like washable markers and children's art supplies, allowing for creative expression without the worry of permanent stains. This ink is formulated with special ingredients that break down when exposed to moisture, making cleanup simple. Many washable inks are non-toxic, making them safe for use by children. They provide a fun and mess-free way to enjoy art and writing while ensuring that any accidental marks can be easily washed away.
