More like paint on a canvas than chalk on a sidewalk, these spongy rollers encourage kids to create colorful, colossal artwork (or a hopscotch game board) that can simply be washed away to provide more room for more creativity. Simply add water and shake to create nice, thick chalk-paints in hues of red, yellow, blue, purple, orange, and green. For ages 3 and up. • Set of 6 liquid chalks in roller bottles • Easily "paint" colorful, colossal artwork • Great to use with our ChalkScapes® stencils (sold separately) • Just add water • Includes red, yellow, blue, purple, orange, and green
