A reusable drawing mat lets young children create glowing graffiti art with water, offering a mess-free activity for kids aged 3 to 6. This set includes 20 pieces in a color box, with the mat made from durable material that reveals bright, luminous effects when wet and fades as it dries, allowing endless creative play. It is designed for early learning and sensory exploration, helping little ones practice drawing and writing without ink or paint. Sold wholesale by the box.
