I got this gel/liquid pouch alongside a purchase from H&M two weeks ago. The saleswoman didn't say anything about it (just threw it in there alongside a free set of earwarmers...) and I forgot about it until now.
The plastic seems quite thick and that little metal piece in there says nothing on it.
Does any body have any sort of ideas or guesses at to what this could be?
Try clicking the piece of metal. The liquid should start turning solid and will release a huge amount of heat. It lasts for around an hour, so they're great to put in your pockets on a really cold day.
