---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- Size: External dimensions: 138mm long x 12mm diameter (maximum diameter 17mm) Color: Black Materials: Body, Cap: Polycarbonate, Acrylic Resin, Polypropylene, Stainless Steel; Nib: Stainless Steel; Cartridge: Polyethylene Resin Ink type: Water-based (dye type) Country of Origin: Japan
