This is a PMC-made belly band. Retail price: ¥36,300 (tax included) My mother, who suffers from cold sensitivity, used it a few times and then stored it for a long time. It shows signs of use, so please refrain from purchasing if you are sensitive to this. It has been home-cleaned. The size is approximately 38 x 20 cm when laid flat. There is no bag, but according to the PMC brand page, "Natural mineral stones are printed on the abdomen and back. It improves the function of the stomach and intestines, and is also recommended for those with lower back pain. *Please use with the mineral stone print side against the skin." The effects may vary from person to person, so we cannot guarantee them. Please purchase only if you understand this. Thank you. (._.)
