Although this product has not been approved by the moderator, I decided to give a little encouragement. Why ?, because this is quite unique and useful.

Well, I will definitely buy this kind of product because I can keep food cool anywhere.

Oh yes, how long is this product able to withstand the cold?

Note:
I'm sure your hunt is undervalued and it's right to get help to crawl up to the better ranking. Why ?, because i think it's "COOL".
