------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------

A combination of firefly glass, popular in Okinawa for its glow-in-the-dark properties, and terahertz technology. ■Size: 8mm diameter (±0.5mm), 24 beads; inner diameter 160mm (±5mm) Firefly glass is a type of luminous (phosphorescent) glass that glows in the dark. Each piece is crafted by artisans who melt colored glass, roll it around an iron core, and then layer silver leaf onto the molten glass, which resembles syrup, using a special technique to create beautiful colors. Terahertz waves emit vibrations that occur approximately one trillion times per second. ◆Terahertz The secret to terahertz ore lies in the energy that causes molecular vibrations to occur one trillion times per second. Terahertz waves (tera/1 trillion hertz waves) emitted from terahertz ore are electromagnetic waves that fall between "light sources such as far-infrared rays" and "radio waves." These terahertz waves possess properties of both light and radio waves, with frequencies ranging from 1 trillion Hz to 100 trillion Hz and wavelengths from 3 μm to 1000 μm.
