200 Pack 5x7 Corrugated Cardboard Sheets for Mailers, Flat Packaging Inserts for Shipping, Mailing, Arts and Crafts Supplies, Dividers, DIY Projects, 2mm Thickness

Your count was off by 5. I didnt recieve the amount that I paid for. This was for a project. Please count correctly when packing orders. Otherwise great product.

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 **

These 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!

These 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!

So I needed something to keep my handmade cards from bending. I typically use rigid mailers for etsy orders, but these are going to be used specifically for FBA. These are so much more sturdy than my rigid mailers and so lightweight! Great product!

I am more than pleased with these pieces of cardboard. They are thin but extremely sturdy. Perfect for my card business shipping. Came packaged VERY well. Would buy again.

I purchased this product from the seller on Amazon and I am thoroughly impressed. It surpasses expectations with its exceptional durability, flawless performance, and intuitive user interface. I wholeheartedly recommend it.

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.

These are PERFECT for shipping cards, postcards and other items you dont want to bend. These pieces are actually sturdy and rigid, which is not always the case. They are also pretty lightweight so they dont make your package too heavy. Just what I needed and Ill be back for more.

I 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!
