I was organizing my garage and wanted a better rack or boxes for my and family expensive shoes. I recently saw people using transparent boxes to keep shoes and stack them. I liked the idea that its a neat way to show off expensive shoes. These boxes are very sturdy and quality construct. Its expensive but worth the quality. Boxes are big enough and stacked easily on each other. 4 in the box, easy to assemble and stack. Assembly does need little force and alignment. It tool me a while to assemble first but the next three were fairly easy as I got the trick to assemble it. The plastic is clear and thick. Its a no nail assembly which is the best part. No nails no screw, just interlocking, making it super strong. Other than price, this product is best in quality and sturdiness
