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

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.

These were exactly what I was needing for packaging art prints. Great value for the money. I will 100% be buying more in the near future!

I used these for my business and mail stickers in between. Since I started using these, I havent had any issues with mail bending. These are thicker than I thought!

We use these in our store bags for support and product dividers. They work great and wish we would have found them several months ago.

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!

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 **

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.

I ship out trading cards, and I use these in the envelope, so the card doesn’t bend. These things are VERY stiff, and work amazingly well.

I used these for an art craft. They were very sturdy, but required a lot of glue to get string to stick. It did the job, but was pricy for cardboard.
