This is a Sumikko Gurashi hot pack. I used it once and then stored it in a bag. It's in good condition, but if you look closely, the side of the nose seems a little yellowed. Please check the images. It's a reusable hot pack. It's the type that you heat in the microwave. I will sell it to someone who understands that it has been stored at home. #SumikkoGurashi #HotPack
