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

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.

The product was used to make Thanksgiving Trees

Price is a little high for cardboard

Great quality. Very sturdy!

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 quality, but all sheets were warped. It might not be a big deal for shipping, but I want to use them in a laser cutter.

A lot of them are bowed, and I cannot get them to be flat. The pieces that are flat feel very sturdy and great for shipping sheet music. The box it came in was ok, so Im not sure what happened. If they were all completely flat, itd be perfect.

This 1/16 Cardboard is perfect for making jigs on my GlowForge! Rigid and Smooth. Will buy again!

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

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.
