Serpentinata Benjamin is a ballpoint pen produced with 3D printing. All parts except the refill are 3D printed. The pen is transparent when new and gradually turns yellow with use, especially when exposed to sunlight. Yellowing of plastic under ultraviolet light is usually seen as a defect in industrial products, and Serpentinata Benjamin treats the change as a positive quality. Each pen develops its own color over time, in the way that musical instruments, leather goods and wooden furniture age with their owners. The pen measures 9.5 by 9.5 by 105 millimeters including the cap.

- Unique Properties
- Depending on the material, plastic can turn yellow under the influence of ultraviolet rays. This phenomenon, known as “yellowing,” was originally frowned upon and regarded as a bad thing for industrial products.
The 3D printed ballpoint pen “Serpentinata Benjamin,” is designed to tackle this new interpretation of plastic. It reinterprets the negative phenomenon of yellowing plastic into a positive one. - Dimensions & Packaging
- W9.5 × D9.5 × H105mm (including cap)

- Production Technology
- All parts of the pen aside from the pen refill all use 3D-printing technology. The newly 3D-printed pens are transparent in color at first, and later turns yellow the more exposed it is. The yellowed pen in the picture takes place six months after use.
- Project Duration
- This project started at Japan.
- Operation Flow
- The pen will be transparent in color when the user first start using the product. It will then turn yellow the longer you use it, especially when exposed to the sun.

- Products such as musical instruments, small leather goods, and wooden furniture that are used by people over a long period of time become their own unique colors.
