---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- This is a crystal of the metallic element bismuth, atomic number 83. A beautiful rare metal. The iridescent colors on the surface are due to an oxide film formed when it reacts with oxygen during recrystallization. Its charm lies in its unusual crystal shapes and colors, its iridescent sheen, and the way its appearance changes depending on the viewing angle. The diverse colors are produced by the same principle as the oil film on water or soap bubbles: light is diffracted by the oxide film on the surface. The name bismuth is said to originate from the German word (Weiße Masse, meaning "white mass"). The color and shape will be random. Each metal crystal is one of a kind. Please note that there may be a weight variation of approximately plus or minus 10%. This is a crystal of the metallic element bismuth, atomic number 83. A beautiful rare metal.
