This is a novelty item from merry jenny. It seems to be able to keep things both hot and cold, so I think it can be used all year round. It's new and unused, but I took it out of the box once for the photos. Although it is unused, please refrain from purchasing if you are sensitive to such things. It will be shipped in its original box. Immediate purchase is welcome ◎ Price reduction is not possible, so I'm sorry, but please refrain from comments asking for a discount.
