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

Thanks really great

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 bought the 5x7 size and they are a must buy, seriously amazing quality!! I use these to ship paper products for my business and I am SO thankful to have found these after two years of a bad experience with another Amazon seller. For some reason this product is hard to find on Amazon. My photo shows the quality difference side by side. The old ones always arrived wrapped in zip ties which left them badly bent every time. These new ones arrived neatly stacked in a clear bag that kept them perfectly straight. They are very sturdy too. I never leave Amazon reviews but these will make my life so much easier. Will be ordering a lot more today because I never want to run out!

True to size and great for packaging items or putting backing in a frame

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!

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.

Needed these for shipping small paper products. Found they fit in the envelopes well and my customers thank me for using quality cardboard to protect the antiques. I will be ordering more.

Super good quality and perfect for adding backing for flimsy envelopes Package came in a neat stack, easy for storage Fits perfectly in my A7 envelopes and match the kraft paper

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

These are very sturdy and perfect for packaging fragile items.
