> 3 dayA 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.

> 3 dayI 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.

> 3 dayNow 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.

> 3 dayI 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!
