Query: Happy with purchase

I'm happy with my purchase. The mats are nice to wrap around food containers and bottles so the cold surrounds them. They are lighter than the typical blue ice blocks. The only reason I didn't give them a rating of 5 is that I think they are easy to puncture if they get poked or rub to hard against things. The pros are greater than the cons and I would purchase them again.
