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

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.

I 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.

Definitely helped me with my projects

Thanks really great

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.

Durable and easy to assemble

They came warped and not flat. Extremely thin. No protection what so ever.

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!

I’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.

It is for sure sturdy and it’s not thick which is what I like I needed small for journals! If you are expecting it to be big it is not for you or if you want it thick! But I love it so much !!!
