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

Arrived in perfect condition! This was packaged with care, it came in a very clean package. It is very sturdy cardboard. I would recommend this product for shipping.

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

Perfect for my shipping needs!!

These are very sturdy and perfect for packaging fragile items.

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 **

As ridiculous as it may sound, I am so impressed and excited about this cardboard! It is not your standard cardboard that bends or dents easily. It is incredibly strong yet thin, not sure how that works but it does! I wish I had discovered these sooner. Highly recommend.

These are exactly what I needed to ship out paper goods without them bending in the mail. I am so glad that they came undamaged and better than I thought theyd be. Will purchase again.

Thanks really great

This product is horrible not useful for anything

The cardboard sheets were shipped quickly, packaged well, and were great quality.
