I use these in my stiff envelope mailers for my art. They work great. Nice thickness, but not too heavy

Really strong carboard for how thin it is. I use it to ship my prints and even mousepads (to give a little support when shipping) and they work really well! I'll be purchasing these for my small business from now on! :)

These are good quality supports for making different format proof of concept packaging. They are the perfect size for my projects. They are sturdy and have a lot of utility! If they were less expensive I would be even more satisfied.

They are quite thin as far as cardboard goes. I use them in a plastic sleeve to protect my artwork and will continue to use them - but I wish they were thicker
