I made copper wire coils inspired by the Maruyama Black Eye. Total of 10 copper wire coils * Copper wire thickness: 0.7mm Sizes and quantities: Approx. 2.1cm x 2 Approx. 2.4cm x 2 * Copper wire thickness: 0.9mm Sizes and quantities: Approx. 2.7cm x 2 Approx. 3.0cm x 2 Approx. 3.3cm x 2 One square on the graph paper is 1cm. A buyer with electromagnetic hypersensitivity commented that they could recommend this to others. (Excerpt from the original text below) "I have been using this product, and it has been very effective for me. I place the larger coils (for low frequencies) on appliances, hard drives, and servers at work, and the smaller coils (for microwaves) under my pillow and behind my PC screen. Furthermore, by using multiple coils of different sizes on electrical appliances, I felt a similar effect to Dr. OO's product, Arshi OO. I think those with electromagnetic hypersensitivity will especially understand the feeling. I highly recommend trying it." They left this comment. Also, another buyer asked, "Will it still be effective if I bend it?" So, we, the buyer and I, the seller, experimented with wearing a bent coil like a necklace to see how it felt. Here are the results of that experiment. The buyer had whiplash from a collision accident about two months ago. The following is an excerpt, with some modifications. ↓↓ "The stiffness and shoulder pain were relieved, and I felt incredibly light. But, being skeptical, I... experimented by not wearing it the next day, and the shoulder pain returned^^; stiffness in the neck and back. Also, when I wore the coil before bed, my shoulders and neck were relieved. I was really surprised! Is it really good for the body? I still can't believe it." They gave us this feedback. (Both opinions areあくまでも個人的な感想です。Please understand that these are personal opinions.) I make these with care, but they are handmade by an amateur. The spacing may vary slightly depending on the force applied at the time, and there may be slight imperfections or small scratches. There are also some areas that have discolored since the copper wire was purchased. Please understand. You can see other copper wire coils here. ↓ #KitoCoil We offer a 100 yen discount from the total price for the second item onwards. A 200 yen discount will be applied for three items.
