Enhanced electromagnetic wave protection: "Black Eye Gaius Necklace" Retail Price: ¥16,500 Developed using the Maruyama-style coil, a unique blend of nano-ceramics, and the interaction of geometric figures, this necklace is called a "miracle pendant" by its developer. It features a double-sided design, allowing you to wear either the multi-layered Maruyama-style coil side or the Kamuna figure (※) side facing out. I purchased it and used it for about a week before storing it. Please refrain from purchasing if you are particularly sensitive to used items. We regret to inform you that cancellations and returns are not accepted after purchase.
