Shipping will be via Yu-Packet Plus. (No report or pamphlet will be included.) I received this from a local salt shop, but I have more than I can use, so I'm sharing! ⋈*。゜ This is Himalayan rock salt (black salt) mined in the Himalayas. ⋈*。゜ Black salt is said to have strong oxidation-reduction power, and it has a sulfurous scent, allowing you to enjoy an onsen (hot spring) experience at home. ⑅︎◡̈︎* *When using in the bath, please be aware that reheating the water or using the remaining water may cause malfunctions! It can be used for food, but as it is a natural product, foreign matter (such as sand) may be mixed in. At home, we use it as a powder with a grater. (*´▽︎｀*p♡︎q It doesn't have to be a special rock salt grater; a 100-yen shop one is sufficient to make it into powder. ⋈*。゜ As it is a natural product, some pieces may be wet or have a white coating on the surface, but we appreciate your understanding. ⑅ *✲゜*。
