Box USA Double Wall Corrugated Cardboard Sheets, 36" x 48", Kraft (Pack of 5), (BSP3648DW)

I needed to ship a couple of large canvas mounted paintings that I had already thrown the boxes out for. I bought this cardboard to build new boxes. The cardboard arrived at my building wrapped several times in movers plastic. The corners got a little smooched in transit, but nothing that was too noticeable, and for my purposes it didn't really matter anyway. But if you are using this for some kind of precise art project or something where you need the cardboard to have perfect edges, it might bother you. They could do a better job of shipping it I guess by simple putting some corner protector pieces on each corner. Anyway, that aside, I was very pleased with the quality of this product. It was very strong and firm. The double wall sheets were easy enough to cut to the sizes I needed with my box cutter, but yet still strong enough to take some effort to bend. I felt very confident that the paintings would make it to their destination without damage. I would buy it again.

I used this as backing for some large maps and attached the maps with contact cement. Very good quality for this. Only suggestion is the company should use cardboard corners. When the cardboard was strapped for shipping the outer sheets had the edges crushed. But, a great quality item at a good price.

I was looking around for a long time for the perfect type of cardboard for certain art project for the backing, and after a long hard search found this. It is a little bit more difficult to cut through and manage, but it is the firmest cardboard I could find they acted well to keep my artwork from buckling once I attached it.

Works for what I need. It showed up a bit beat up, but Im painting over it. Progress pic. Haha.

I bought this to reinforce a box to ship a picture. It worked great, very heavy duty.

I needed cardboard for a school project in college. After much research with comparing the best cardboard styles in relation to cost, sturdiness, and sustainability I found that this type of cardboard was best. It provides great sturdiness and strength relative to its low cost. Works so well that I ended up replacing the dorm chair with the newly built chair. Mostly so I could see the TV captions for once since the dorm chair was much too small. Any excess cardboard can be used to make a mini-bed for your dog or cat.

Yes, these are sturdy and the ones I received are double corrugated, but some sections of these would still bend and weren't as sturdy. I needed these to sturdily package paper prints of my artwork. The 5 sheets came wrapped in a lot of plastic which provided barely any protection. This was my first time buying cardboard, as I always reuse the cardboard I have around but didn't have any this time. So, for the amount of money that I paid, I expected all 5 sheets to be in good shape for my projects. Not only was 1 corner of all 5 sheets damaged and unusable, but the outer 2 pieces that were wrapped in plastic were covered in dents or bent, and I only had 3 pieces that were in good condition for my project. This was a waste of money because I essentially paid for damaged cardboard and garbage. I could get better quality cardboard for free elsewhere, but was hopeful that paying for it could buy me out of the inconvenience of looking for it. Needless to say, I was very disappointed with this item. It overall did the job I needed it to do, but it's not worth it if you need pristine, high quality cardboard for something like art protection.

I need a box in a size that wasn't available. These corrugated sheets let me create a box in the size I needed. The double wall construction allowed me to create a sturdy box. They came well packaged to avoid damage. Great product, I would buy them again.
