Bests & Worsts Reviews from Amazon

Previously I would have given these boxes a 5 star rating. I know they can be a bit rough around the edges and are packed and shipped only bundled and wrapped in overwrap. But they've suited my purpose and been of good quality. However, with my last purchase in March I bought 2 bundles of 50. I sell online and just needed to open the second bundle today. Approximately 1/3 of the boxes are defective, with over 1/5 of them being unusable. The white layer is improperly affixed and wrinkling and peeling off. Corrugated gets its strength from the layering... remove a layer and it just crumples. If I had opened both bundles immediately I would have caught the issue and requested a refund. I'm past the window now and am short 12 boxes that I can't use. Word to buyers - INSPECT your entire order upon receipt. Cut the bundle tie - these boxes were in the interior of the bundle and not visible as defective until the stack was separated. UPDATE!!! 12/5/2019 Well, I thought despite my last quality issue, that I would try again. This time I bought just (1) 50 pack of the M432 mailing boxes. Quality has plummeted again. Corrugated cardboard is about half as thick as before and the paper covering is different, with a noticeable off-white tinge. I could deal with the less clean, cheaper-looking color, but it's a much flimsier. Just handling the cardboard to assemble it causes it to bend and give. It feels like you're handling cereal box board. Once assembled it feels less sturdy. This doesn't seem to be a cut in material quantity as both boxes weighed 35g, but more of a compressing/flattening of the corrugation. As mentioned in my earlier review, good corrugation quality is what gives the material strength. Ugh. So done with this product.
