Perfect for sandbox play! The neat thing about this Tolo Rainbow Stacker from Small World Toys is that each cup has a design in the bottom, so kids can make awesome sand molds with stars, triangles, flowers, and more on the top. Cups can be stacked all on top of each other, or nested for easy storage. Kids will love these bright shapes and colors. Great for developing hand-eye coordination and other cognitive and motor skills. Largest cup is approx. 3" tall. For ages 6 months and above.
