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

Nice and sturdy, but really light!

This product is horrible not useful for anything

These are very sturdy and perfect for packaging fragile items.

Durable and easy to assemble

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!

This 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.

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.

I 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.

You get a lot for your money. Perfect to use with mailing.

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.
