Packit Freezable, Durable Lunch Cooler, Soft Mint, 9 Can Capacity

I opened this up and wiped it out, then flattened and put in the freezer. This lunch box does not take up a lot of space and is very roomy. After it being in freezer all night the next morning I removed and packed my husbands lunch. I also put a couple of cold drinks in. He and I were both surprised that the drinks and everything else inside stayed cold. It was so nice not having to add extra ice packs or anything. This is a very good idea someone had. Cleans up easily and ready for freezer.

I kept it folded on refrigerator for night as per the instruction and in morning, just to test, I put a small container of hummus with leafy salad in it and a soda can inside to see how long they remain cold. And it worked really awesome. After 3-4 hours, when I took the soda can out, it was chilled. Salad was cold and fresh.
