Selling because I don't use it. I opened it to check, but I haven't used it even once. There are some scratches and dirt on the outer box due to home storage. - Product Name: IL-CORPO MINERAL BATH STONE - Contents: 600g - Package Type: Mesh case included - Brand Name: Sì BODY "Mineral Bath Stone" is a natural bath additive that luxuriously uses the rare natural stone "hornblende" mined only in Tono, at the foot of Mt. Iwate in Iwate Prefecture. Far infrared rays emitted from the natural stone create a feeling like a rock bath. Please enjoy a gentle time that gently envelops you. Thank you for looking.
