  • PERFECT!
Size: 5x7
I use these to wrap fabric on so it can be stored in a bookshelf. Works perfectly

  • Could be a bit thicker and sturdier, but is somewhat suitable for the price.
Size: 11x14
It is a decent value, but not quite as solidly put together as I expected.

  • Thin, rigid - fits the bill.
Size: 8x10
I am using these cardboard sheets in an unconventional way - for a papier mache project. Wanted material to build structure without lots of bulk. These thin rigid sheets are perfect - and easy to cut and shape.

  • So useful
Size: 8.5x11
There’s literally a million things you can do with this. I used it as backing for my seven year olds bookshelf. So far it’s held up surprisingly well. It’s really sturdy. I also made photo props with it, cardboard cut outs, decorations and so much more. I mean the possibilities are endless with an exacto knife, hot glue, and some paint! ... show more

  • A Surprisingly Great Value!
Size: 8.5x11
I needed something to back some 8x10 prints that I was going to put in clear cello bags. I also wanted something that looked clean, as presentation is key. It took only 2-3 days for these to arrive. They came securely packed in a cardboard box and every piece is flat, undented, and clean-edged. I am impressed. They fit my cello bags perfectly, support my prints, and don't look cheap. The cardboard pieces are thin, which I wanted, but sturdy and strong and for this purpose, they are perfect. They are a good price and don't add a lot of cost to my prints - overall, I am very pleased. ... show more

  • Good cardboard
Size: 8x10
It is quite thin — thinner than I expected — but very strong and rigid because of the narrow corrugated channels and it will provide good protection when I mail greeting cards and other paper goods I make/sell. A very good product for that and I would definitely buy it again. I would have also said it was a good value, but I see that the price has increased 50% since I ordered it — eight days ago!!! That is some pretty outrageous “inflation” in a very short amount of time! That’s why I am giving it four stars instead of five. ... show more

  • Sturdy product
Size: 5x7
This cardboard is strong enough for craft projects and holds weight well. Good value for the money.
