This product is used to back professional artwork and prints for sale.

I purchased this product from the seller on Amazon and I am thoroughly impressed. It surpasses expectations with its exceptional durability, flawless performance, and intuitive user interface. I wholeheartedly recommend it.

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.

I Love these :D they fit inside my 5x7 envelopes :D

These are absolutely fabulous for mounting 5x7 magnet sheets onto and storing craft dies! Great quality cardboard, clean and smooth, as well as packaged beautifully! Will order again as soon as I fill up all the sheets in my first order!

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!

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.

Insert for mailing flash drives

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.
