A necklace model made of high-durability black ceramic. About Black Ceramic Also known as "artificial diamond," the black ceramic (zirconia ceramic) used boasts excellent aesthetics and durability among ceramics. In particular, it is known to have a hardness far exceeding that of general stainless steel in terms of durability, making it highly resistant to scratches. It is lightweight, about one-third the weight of metal, and is also metal allergy-free because it is non-metallic. It also feels less hot or cold and blends with body temperature. It is not affected by discoloration due to ultraviolet rays or magnetism. Ceramic is a sintered body made by heat-treating and solidifying inorganic substances. The melting point temperature during the heat treatment of black ceramic exceeds 1,000 degrees Celsius, and it is also attracting attention as a heat-resistant material. The main component of Coreforce powder is minerals, but the difference in melting points is significant, and it cannot be mixed into black ceramic using conventional methods. To solve this problem, engineers repeatedly experimented and added ingenuity to withstand high heat, and finally succeeded in incorporating it, giving birth to the "Coreforce Neck Pro." ◆ Color: Black系 (Black-based) ◆ Approximately 50cm Necklace ◆ This is an authentic product.
