---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- Ore set Ore specimen set Collection Set Rock specimens Jewelry toys ◆【Mineral Collection】 Among them are famous stones such as amethyst, rose quartz, and obsidian. ◆【Even curious children will be very satisfied】 A set of 48 natural stones and minerals. ◆【Very popular as a gift】 Perfect for Children's Day, Christmas presents, birthdays, and more!
