Mess free painting fun is a creative experience unlike any other, and Color Wonder Paintbrush pens make it possible. The kids paints in this set magically appear on specially formulated Color Wonder paper (sold separately), and not on skin or clothing. These pens are the perfect refill for existing Color Wonder art sets at home, or to start off your collection by pairing these with Color Wonder coloring pages of your choice! Give kids a real, tactile experience of painting, without having to clean up a mess in the aftermath. Color Wonder activities make the perfect gift for kids ages 3 and up.
