16x16x16 Moving & Shipping Boxes, Extra Strength, Heavy-Duty Corrugated Cardboard Boxes for Packing, Storage, Shipping (5)

Glad I got these heavy duty boxes as anything flimsier would not be able to support weight vs size ratio. Good size for handling items which do not fit in banker file sized boxes.

I did not receive “heavy duty”, “extra strength”, nor “double-wall” construction boxes after paying nearly $5/box and waiting for them. I received single-wall construction cardboard boxes that are damaged, despite being shipped in a box. I received the box of boxes damaged with a hole punched through the side wall of the box… and they appeared to be at first glance “double” because they were packaged “doubled up”. But after assembling one, it was clear it was just a large single wall construction flimsy box, which Google Lens confirmed. It's so unfortunate since I desperately need them to ship very large fragile vintage items. In addition, at least one of the FIVE boxes I received was ripped. Now I get to start all over again looking for “HEAVY DUTY” boxes to fit my items and make a trip handling a large awkward box of boxes to my nearest Walmart to return these. Attached are the maximum number of photos allowed (FIVE) showing all points I've mentioned, and a side by side grid photo of the side wall of these boxes—one pic from a farther distance and the other as close as I could get it to the camera—proving it is not “double wall” construction. A double wall construction box would have two layers of the wavy corrugated medium or fluting—which would be double what is highlighted in my photo. Per Google Lens “A double wall construction box would look different from the single-wall box pictured (highlighted) in the image because it would have two layers of corrugated board instead of one.“

Boxes are not square %26 hard to line up the flaps (that were taped!) Cheaply made.
