This is a silica concentrate (silicon) made with Kirishima, Kagoshima spring water. It is a set of 18 bottles. Silicon contained in silica water plays a foundational role in the body, composing all cellular tissues such as hair, skin, nails, bones, muscles, brain, internal organs, and blood vessels. Adults are said to consume 10-40mg of silicon per day. Therefore, by utilizing water-soluble silicon, it has become easy and convenient to supplement silicon. This product is a concentrated type, so it can be mixed with water to drink, and can also be used in cooking. I purchased a large quantity but couldn't use it all, so I am selling the surplus. Of course, it is unused. Add 5-10 drops to a glass (200cc) of drinking water and drink it at least twice a day. Please take advantage of this opportunity. * Expiration date: March 18, 2027 * Reference price: 4,752 yen / bottle (tax included) * Purchase date: April 2025
