● Maruyama-style Coil BLACK EYE Black Eye 11 pieces ● The product includes only the main body shown in images 1-3; accessories, a dedicated box, and dedicated stickers are not included. ● I didn't use it much after purchasing it, and it was stored in a desk drawer. ● The "Maruyama-style Coil" is a mysterious coil that transforms electromagnetic wave countermeasures into good energy. By addressing electromagnetic wave countermeasures that affect humans in various ways, it helps to balance our minds and bodies as we live surrounded by electromagnetic waves. It can also be expected to improve circulation in the body through the effects of far-infrared rays. And, the "Black Eye" was born by utilizing that technology. The "Black Eye" is a sticker that works on the weak bioelectric current flowing within the body. It not only relieves stiffness but also brings out your original power. The appeal is that anyone can use it anytime, easily! 【Information】 ・Please understand that the color may differ between the photo and the actual product before purchasing. ・Please understand that this is a used item, and we ask for no claims and no returns unless there are special circumstances after purchase.
