Love this sandbox but more importantly my 3 year old adores it!! Wants to play every day with it which is great! I filled with gravel - so much better & cleaner/ less sticky than sand, plus he can really scoop & dump w/ his construction trucks! He's big for his age but still plenty of room. Lid fits well- does not seal completely but seems to keep it dry. This is such a great deal, great size, and holds a lot of toys! You won't be sorry if you purchase.
