Combine fresh air, sunshine, and creative play with the Hop Scotch Sidewalk Chalk by eco-kids! Perfect for encouraging movement and imagination, each egg-shaped piece is easy to hold and great for little hands. Plus, all colors are quickly washed from sidewalks and driveways, so when it's time for a blank canvas, simply rinse away and get back to drawing!
These do work pretty well on sidewalk, although they are pretty light. They do not work on a regular chalkboard which I was hoping to use for both. So I still had to get regular chalk in the end.
