This sand box is below any reasonable workmanship quality. The wood planks are fastened with flimsy staples that come apart while putting together the box. This could be SERIOUSLY DANGEROUS because if staples are exposed while child is playing in the sand it could get HURT puncturing hands, feet, face etc. if child would fall on the exposed staples. Beside the safety issue there are some other problems such as the provided screws are not rust resistant (not stainless steel, aluminum or galvanized) and the item is meant to be used for outdoors exposed to weather elements. I suggest that you stop selling this product in the present form or make some necessary changes.
