I purchased this last October and only had it in my room for about three days. After that, it was just stored, so I think it's practically new. The Spinor Room is an electromagnetic wave countermeasure product that is currently a hot topic. It doesn't fight electromagnetic waves, but rather harmonizes the space. It is effective for one room. Size: 8.5 cm in diameter, 1.5 cm thick, and weighs 108g. Place it horizontally with the front side up. Compatible with 5G. Made in Ukraine. Patented in the United States and France. The effect is permanent. Purchased on Rakuten Ichiba, the current price is 33,000 yen. Please consider purchasing it.
