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

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!

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.

Ive brought these before but this batch was completely warped. I use for shipping books and it warps the books. Useless. edit: ordered again to see if it was just a fluke that they were warped. it wasnt. 2nd batch was warped too. probably due to how they ship them

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

What magnificent cardboard sheets! I had to trim them a bit to fit my mailing envelopes, but they are sturdy without being thick. I use them when I mail music books, which get damaged if put into envelopes without support.

I spent an alarming amount of time trying to find a cost efficient and good quality solution - this is it. I can put these in a sleeve with the art, ship them in a poly bag, and they arrive save and sound (provided USPS doesnt decide to take my fragile stickers as some dumb personal challenge).

Used with a glowforge later cutter perfectly.

I use them for keeping my products flat for shipping and they are spot on. Will def order again.

Just what I needed to sell prints of artwork. These + plastic sleeves are perfect for customers to pick up an item and carry it without worry it will bend.

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