I can't answer because the Altman pen is a fictional object, and there is no specific method to make it. Maybe you can design and make a pen similar to the Altman pen yourself, but the specific manufacturing method needs to be based on the design material and shape. It is suggested that the design scheme and materials used should be determined first, then experiments and practices should be carried out, and continuous attempts and improvements should be made to finally get the Altman pen that you are satisfied with.

　　There are many ways to make ultraman pens, which can be made with different materials and tools. First of all, you need to prepare a refill and a pen case. You can choose ordinary refills and transparent pen cases, or you can choose special Ultraman refills and corresponding Ultraman pen cases. Then, the pen case can be wrapped with colored adhesive tape or colored plastic sheet to make the appearance of Altman. You can also use carving knives, branding brushes and other tools to portray Altman's various lines and decorations on the pen shell to make it more realistic. Finally, put the refill into the pen case to ensure that it can write normally, and the Ultraman pen is finished.
