> 3 dayI use these to back my sticker orders! Absolute lifesaver to make sure my Etsy Shop (@EmbroideredEyesores) items don’t arrive to customers bent or scuffed up! Love these!

> 3 dayThis is hands down the best to pack prints. They are thick and sturdy and keep prints safe when shipping out to my customers. I recommend these backing boards. They are true to size and come safely packed.

> 3 dayA little pricy but seem to be of good quality. They are pretty thin but seem surprisingly stiff considering their thickness. They are also quite smooth. I purchased these for use as stiffeners in padded mailing bags for use in shipping small items. They might be a little smaller than ideal for use in a 6x9 inch mailer but I think theyll probably work out for that OK. These would probably work nicely for a lot of arts and crafts projects too. They measure exactly 5x7 inches and 0.079 to 0.080 inches thick. I hope this info is helpful.

> 3 dayI needed this to protect some prints that were 5x7 inches, but the cardboard, while sturdy & decent quality, isnt exactly 5x7. They are slightly smaller in both width & height, so doesnt work for my purpose. Really annoyed.
