TETZBO Chibien Length: 74mm Made of brass, it consists of three parts: the body, the lead, and the screw. The lead is secured with the screw using a hex wrench. Pen stand: 40mm x 35mm x 25mm The lead uses Mitsubishi Jetstream refills. 4C standard refills can be used. Due to the properties of brass, the color will change over time and with use. I think there's enjoyment in watching it develop. Polishing with metal polish, such as Piccal, will make it look like new. This item has been handled by someone else, so we would appreciate it if you would consider this before purchasing. Thank you very much.
