Thank you for viewing. This is a set of 5 "Awa Kara Suiso" face wash foaming nets from Chojyu no Sato. I am selling these because I have accumulated too many. The hydrogen balls (ceramic balls) inside the net generate hydrogen every time they come into contact with water, trapping it in the foam, allowing for a face wash suitable for anti-aging care. It lathers very well with face washes other than "Yokasekken," as well as with solid soaps and body washes, allowing you to wash your face and body with fine-textured foam.
