Thank you for viewing! ^_^ This Bakuhanseki stone originally contained 800g, but approximately 1/3 was used, and the remainder has been stored. It's Bakuhanseki from Mino Shirakawa, the only place of origin in Japan. It's a mysterious stone said to create delicious mineral water ♡ Approximately 285g of the original 800g was used. The remaining 515g is being offered. *The package has been opened, but the contents are unused. For those who understand the above...☆ Thank you very much (♡ᴗ͈ˬᴗ͈)
