[Material] Main body made of stainless steel (glossy treatment) [Size] Outer shape 15mm, total length 56mm [CMC filling amount] Approx. 1200mg [Weight] Approx. 27-28g CMC (carbon microcoil) Carbon fiber wound into a coil shape with a pitch of approximately 0.01 to 1μm (nano-sized ones are called carbon nanocoils (CNC)). It has properties such as absorbing electromagnetic waves, and is expected to be applied in various fields such as protecting cardiac pacemakers. It was developed for the first time in the world in 1990 by Seiji Motoshima, professor emeritus of the Faculty of Engineering at Gifu University.
