Review on Enhanced Instapak Quick Temperature Expanding Packaging by Brian Whitmore

I usually use a pair of Uline long/larger ones, of which I usually only need 2 because they are so long and wide. However, I was traveling and didn't have time to order from Uline so I ordered these thinking they would be smaller and I would probably need to use at least 4 to secure my item on the top, bottom and sides. Well, as an experienced person, I knew I could spread the foam a bit very quickly because you need the foam to sort of fill the bag. At the same time, the foam was so thin that it was practically unusable for a 3D object. I ended up having to use 8 and it probably wasn't enough to cover it completely so I had to add $28.90 of bubble wrap and gift wrap (just for their amount) to wrap this item, that would have been $16, if i had used those in uline because they are so thick you can slide your item down and then only put 1 on top! They work but not for 8x8 if you want to use them as 8x8.
