50 Pack Corrugated Cardboard Sheets 6x9, Flat Packaging Inserts for Packing, Shipping, Mailing (2mm Thick)

Nice and sturdy. Well packed and uniform in size. I am using these for crafting. Cuts easily with an x-acto knife.

I was a bit worried about the thinness but now that I received the cardboard sheets I am actually glad they are thin because they are sturdy and will not bend with normal use. This also cuts down on the storage space needed for these. I use cardboard to mail my watercolor paintings and the size is perfect for my usual 10.2 x 15 " paintings, (I ordered and received the 11 x 17" size). It will be so nice and a time-saver to have precut cardboard available. And or smaller paintings, I can easily cut these to a smaller size with a box cutter. I actually think I could use only 1 to mail my paintings to keep them from being bent, but likely I will use two for that extra degree of protectiveness. I also like that these are without any kind of bending or marking and so they look professional. I'll tie with either washi tape or a paper ribbon and if I add a sticker or stamp design they look nice enough for gifting.

These worked great for my students’ art projects! Thin enough to cut (with good scissors) but thick enough and big enough to work with!

I bought this to put on the back of my art prints when I ship them and it works great doesn’t bend and is very stiff, which is what I wanted

Product was purchased to use in raised garden and its very thin but worked well.

I mean - it's cardboard. However, the cut was uniform and this is the perfect thickness to ship photo prints to clients with.Cut was uniform and well-packaged. Decent value for the cost!

Normally I don't write reviews about cardboard but this product was exactly what I was looking for. I think it could have been cheaper, thus the 4 star rating around value for money, but I needed this for some mailing I was doing. This is not a pasteboard type of cardboard but is corrugated like a cardboard box.

The whole purpose of me buying these is to get flat boards, and each time I buy them (this is the third consecutive batch) they come warped. That means if you lay one on the floor, the four corners don’t touch the floor only 2 to 3 touch, and the one corner will be elevated up to an inch because the cardboard is warped.
