I am very disappointed with the product. This product was damaged and missing hardware from the start.  When I tried to assemble the sand box, I found that piece had been cut wrong, to long, out of square and would not fit. And for the bottom, cheap cloth secured by four small pieces of velcro which someone thinks will hold a couple hundred pounds of sand.  I would have been better off by going to the local lumber yard and bought my own plans and material to build the box.  So thinking I could save this thing, I fixed all of its problems so my four year ago grand daughter would not be disappointed.
