Premium Corrugated Cardboard Sheets 36" X 48" - 20 per Bundle - Flat Packaging Pads - Kraft Double Face - Quantity 20 Pack - for Packing, Mailing, Inserts or Krafts (36x48)

This cardboard is not thick at all. Amazon shipping boxes are better quality than this garbage. It's flimsy and bends too easily. Shipped shrink wrapped with no corner protection, so of course the corners were all dented on arrival. Not worth $100. Barely worth $20. I've written the seller about my dissatisfaction, and heard nothing back from them. Avoid.

These work great to pkge items at work!

PRODUCT WAS THICK AND OF GOOD QUALITY. I USED IT TO SANDWICH EXPENSIVE FRAMED PRINTS. HOWEVER, I WAS SHORTED ONE SHEET IN THE ORDER (19 INSTEAD OF 20) AND HAD TO REPURPOSE SOME BOX CARDBOARD TO FINISH MY PACKING... A REAL AGGRAVATION.
