As Color Wonder Markers only work on Color Wonder Paper, there's never a mess! Color Wonder is a smock-free, mess-free way to color that allows kids the freedom to create without worrying about staining skin, furniture or fabric. Great for toddlers and beginner artists, these markers cut down on clean up time while increasing time for creative play. An ideal gift for boys and girls on birthdays and holidays, pair them with Color Wonder coloring pages or activity sets for a great bundled gift (coloring pages and activity sets sold separately). Safe and nontoxic art supplies for toddlers ages three and up.
