Please ask if you have any questions. This is a 4°C bag. I received it as a gift, so I don't know the details, but it's clean as it's never been used. However, it has been stored for a long time, so there are creases on the handles. They will straighten out if you hang it up as shown in the photo. It's small, so I think it can be used as a pouch or a bag-in-bag. Thank you.
