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.

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!

Using it to divide layers of collectibles. Can bend easily do things stay put.

This product was perfect for the purpose I intended. The cardboard was not too thick so could be cut with scissors to make crafts.

These are sturdy and are great quality. I use these as backing for paper crafts that I sell and I love them. You can cut them down too so you can make them any size!

Price is a little high for cardboard

These came quick(which is fairly standard with Amazon Prime nowadays) and we’re just what I needed. I required something sturdy for packaging artwork prints and these did the job nicely.

I like the strength of this cardboard. Its not too thick or too thin and it sure is sturdy. I have to put some oomph into it when Im folding it. Cardboard is my *go to* product for shipping and all types of crafting and even helps out in the kitchen (cover with aluminum foil for a very sturdy cookie sheet, etc. My philosophy is if you have good cardboard and Duct tape, you can fix anything. Ill definitely re-order this

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.
