This is an ear cuff ring designed by Dr. Seiji Sato of Sato-style Lymphatic Care. There is an acupuncture point called Eifu behind the earlobe. Wear the ring so that the pearl touches this point, and hook the ring inside your ear. The size can be adjusted slightly, so anyone can use it to fit themselves. I have studied the effects of Sato-style Lymphatic Care, received a qualification, and make these handmade. In addition to the lymphatic care, which is said to have beneficial effects on beauty and health, this cuff ring allows you to enjoy fashion. Please make use of it! ^_^ The ring is silver in color.
