I got this for my grandsons. They love to play with kinetic sand and it often gets tracked around the house. This is big enough and deep enough that they can play with the sand and create fun sculptures and the mess can be contained.

I just bought this tray, which is very sturdy for my PreK students. I will not fear that they will break it by leading on it. I do wish there was a top to this tray because my kids will keep coming towards it even when we are not playing with it.
