This is an ear cuff from the Kassarra Koubou. It's an ear cuff that combines high-purity 128-facet mirror terahertz beads, 10mm and 8mm in size. I received this after it was used once, but I have only tried it on. *Please note that pamphlets and booklets are not included. Only the ear cuff will be shipped. <Uses> For issues with the inner ear (changes in air pressure, sense of balance), etc. <Specifications> ・Terahertz beads 128-facet mirror 10mm + 8mm x 2 (Color of terahertz beads: Silver) ・Bead hole filling: Zirconia ・Metal wire: Surgical stainless steel x 2 ・The purity of the terahertz beads is 11N level high-purity silicon. <Effects of Terahertz> ・High-purity silicon emits terahertz energy. ・Terahertz energy is safe for cells. ・Terahertz waves are said to vibrate approximately 1 trillion times per second and are said to regulate the disordered state of cells. <How to Use> Simply set the 10mm bead inside the ear, and the 8mm bead behind the ear. (Adjust the clamping strength. It may fall off if it's loose.)
