    Packaging was hilarious a clear bag of cardboard showed up at my doorstep lol. Using these for my small business to ship prints. They are super sturdy! Great alternative to chipboard.

    I really love these for adding to items to mail to help keep them flat. However, the last batch I ordered is very warped so its difficult to keep items completely flat.

    Nice and sturdy, but really light!

    A 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.

    They came warped and not flat. Extremely thin. No protection what so ever.

    I bought the 5x7 size and they are a must buy, seriously amazing quality!! I use these to ship paper products for my business and I am SO thankful to have found these after two years of a bad experience with another Amazon seller. For some reason this product is hard to find on Amazon. My photo shows the quality difference side by side. The old ones always arrived wrapped in zip ties which left them badly bent every time. These new ones arrived neatly stacked in a clear bag that kept them perfectly straight. They are very sturdy too. I never leave Amazon reviews but these will make my life so much easier. Will be ordering a lot more today because I never want to run out!

    It is for sure sturdy and it’s not thick which is what I like I needed small for journals! If you are expecting it to be big it is not for you or if you want it thick! But I love it so much !!!

    I’ve ordered custom cut corrugated cardboard before, and the quality of this product far outshines even that. These are thin but still incredibly sturdy and hard to bend! And just as a FYI, i would NOT recommend people placing these inside envelopes or flats, since these board are so stiff that your letter will be non machinable by postal services. Since letters and flats are required to have a certain percentage of give/bend-ability, your letters may very well arrive to someone bent and at worst case destroyed. ** parcels/packages/bubble mailers are okay though **
