This is not a "therapy sand tray". I think more people will buy it if you call it that. This box/tray/container will not remain closed. One of the handles fell off on first use and the lid had a small crack. I noticed this after pouring sand into it. I give it back! For the price I thought it would be better and bigger. Measure before you buy! I would not recommend this for sand! Not much space to play at all. I added 3 pounds of kinetic sand and there was no room left for molds or scuppers. You can put coloring books, pencils and the like in this box.
