10 Sets of Hydrogen from Foam "Hydrogen from Foam" that creates the perfect foam. Because it's a long-lived village's original facial cleansing net, which has perfected the material, softness, and structure, it can create the creamy, fine-textured, and correct foam suitable for facial cleansing. The hydrogen balls (ceramic balls) inside the net generate hydrogen every time they come into contact with water, trapping the hydrogen in the foam. This allows for a foam face wash suitable for anti-aging care. *Quoted from the instruction manual ◯Shipping Method◯ Items will be compressed for shipping to adjust the thickness. Please understand.
