Tizas de Acera Gigantes Playground Classics

Bought these for a backyard birthday party and the kids drew hopscotch and a whole obstacle course that lasted through the afternoon. The thick sticks didn't snap even when the little ones pressed hard, which surprised me. Washes off the driveway with one hose spray.

The jumbo size means my four-year-old can draw for an hour without the chalk snapping in half like the thin stuff does. Colors show up bright on our driveway even after it's been rained on a couple times.

My kids can actually grip these without them snapping, which was the whole problem with the thin chalk we had before. The jumbo size means my four-year-old's drawings don't turn into a pile of broken nubs by lunchtime.
