Convenient for commuting in winter, etc., rechargeable Infrared heat belt kidney warmer EG-8DB5 Seller: MOZU Co., Ltd. Product Condition: Purchased in November 2020 for 50,000 yen, with no noticeable stains or scratches. Please refer to the attached instruction manual for the product's features, performance, and the effects of far-infrared rays. I purchased this because I suffered from nephritis and used it in the winter. It kept my lower back warm during my commute. My nephritis has now subsided, and I have retired, so I am selling it.
