> 3 dayI’ve bought these a couple times for my art students. They are a great size. Still find all cardboard on Amazon too expensive for what it is but I don’t have alternative options at the moment so I guess they get my money. I do find them very useful.

> 3 dayI 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.

Greater than one weekThese are very nice for shipping postcards and such for ebay purchases! Would also be great behind photos. They are very supportive....do not bend easily. Much better than another brand I bought in the past. Will be buying again!

> 3 dayThese are absolutely fabulous for mounting 5x7 magnet sheets onto and storing craft dies! Great quality cardboard, clean and smooth, as well as packaged beautifully! Will order again as soon as I fill up all the sheets in my first order!

> 3 dayI’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 **

ummm hey
> 3 dayI needed to use these to send small sized magazines in the mail. I taped two together side by side for a little bit larger surface area and they held up to keep the bubble mailer with the magazine sturdy and unbendable.
