50-Pack Large Corrugated Cardboard Sheets for Mailers, 11x14 Flat Packaging Inserts Pads, Shipping, Packing, Mailing, Dividers, Crafts, DIY Art Projects Supplies (2mm Thick)

Now very warped. I live in a dry environment with low humidity so not sure why they would warp. I tried putting flat cutting board + weight on the package, but no success after 2 weeks. Very disappointing.

Good price for what you get, just keep in mind these are very thin pieces! Still sturdy enough for little models and projects.

I’ve ordered these more than a few times and the last two times have been very warped and crooked. Might work for some but I need the board to lay somewhat flat.

Was not protected during shipping. This is not a first purchase from this seller. Last ones were much higher quality and not damaged. Not happy for the price. Only choice is to send them back Disappointed and embarrassed to use in shipments to protect precious items

Was what I was looking for.

Ive ordered thousands of sheets of cardboard from Juvale. These are my favorite because they are E flute and are sturdy and strong. They work great for making poly mailers rigid. Unfortunately, over the past few months Ive noticed that EVERY pack is warped. That makes it extremely challenging to use them for mailers. No matter how much weight I put on them, they will not straighten. I will be finding another supplier if this issue isnt corrected.

I use these to ship pages of baseball cards, comic books and other bendable merchandise. They are super sturdy, but not heavy which is good for the cost of postage. I found these to be the best for the money. Highly recommend!

I purchased this cardboard to use for extra rigidity when shipping art prints. It is extremely rigid (more so than cardboard used for boxes), and arrived very well packaged with no damaged edges. Very impressed with this cardboard, will be ordering again in the future!

They were great for my moving of oics purposed
