A CMC pendant is a health accessory designed to protect against electromagnetic waves by wearing it, made by encapsulating special carbon fibers called Carbon Micro Coils (CMC) in resin or other materials. It focuses on 5G compatibility and "bio-resonance" to balance the body, and is particularly used by those conscious of electromagnetic hypersensitivity and stress reduction. Features and Functions: Material: Uses carbon fiber with a 3D helical (spiral) structure on the micrometer (μm) scale. Purpose: Expected to absorb electromagnetic waves and reduce their harmful effects. Shape: Often comes in wearable shapes such as magatama (comma-shaped bead) or resin pendants. Use: A health/healing item (supposedly) that protects the body from harmful electromagnetic waves when worn in daily life. *The perceived effects may vary from person to person. - Material: Stainless steel - Design: Simple cylindrical pendant - Chain length: Long chain - Color: Silver Thank you for looking.
