This is an authentic product purchased from the SurvaQ store in January of this year. It's very warm and has a massage function, which I liked, but the pillow was too hard for me, so I only used it a few times and then put it away. The purchase price was about ¥27,000. This winter, it's also very popular, and it seems to be out of stock at the SurvaQ store. How about it for those who want to use it right away? It has only been used once. I will sell it to someone who understands that it is not a completely new item. Thank you.
