---------------------------------------------------------------------- 【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer.

【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. ---------------------------------------------------------------------- Grain diameter 8mm (±0.5mm) Inner diameter 19cm *The photo shows a product with an inner diameter of 16.5cm. Beitou stone is a natural monument in both Taiwan and Japan, and no new stones are mined. This product is made from powdered Beitou stone mined in Taiwan before mining was banned, baked into ceramic. Color can be added by mixing soil or other materials into the ceramic when it is baked. This is a new product that has succeeded in producing a blue color by fine-tuning the ingredients of the Beitou stone powder when mixing it. Made in Taiwan Beitou stone can only be found in the Beitou Hot Springs in Taiwan and Tamagawa Hot Springs in Akita Prefecture. It is an extremely valuable mineral. Beitouite from Taiwan is such a valuable mineral that its theft is prohibited. Beitou stone beads are ceramic balls made by mixing and firing powdered Beitou stone from Beitou Hot Springs in Taiwan to a certain concentration. Beitou stone, which has been featured on television and in other media, emits trace amounts of radiation from its hot spring components. It is also known as the "stone that keeps doctors away." It emits negative ions, and the ion level can be measured using an ion tester. This product is a new product that has been successfully colored blue by fine-tuning the ingredients of the powder when kneading it. Of course, when measuring the values with an ion tester, the values measured are about the same as for normal colors.
