Very poor quality plastic. Was the thickness of a plastic milk carton. Do not buy! 1st time buying anything on WayFair. Return Policy is anything but WayFair. Upon opening the box and seeing how poor quality the plastic was, I put the lid right back on the box. Filled out the return paperwork only to find out WayFair is not refunding me $67 (shipping costs). If I pay to ship the shed back, WayFair will credit me the full amount back. That is not "WayFair" in my book. Save your money!!! Do Not Buy!
