About Serpentinata Benjamin Stilus Sphaerula Scribens

Serpentinata Benjamin est stilus sphaerula scribens arte imprimendi tridimensionali fabricatus. Omnes partes praeter cartulam atramentariam tridimensionaliter impressae sunt. Stilus novus perlucidus est et usu paulatim flavescit, praesertim cum luci solis exponitur. Flavescentia materiae plasticae sub luce ultraviolacea in productis industrialibus plerumque vitium habetur, sed Serpentinata Benjamin hanc mutationem qualitatem positivam esse ducit. Quisque stilus suum proprium colorem tempore acquirit, eo modo quo instrumenta musica, res coriaceae et supellex lignea cum dominis suis senescunt. Stilus, operculo incluso, novem cum semisse per novem cum semisse per centum quinque millimetra metitur.

Behind the Design

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)
Tags: 3dprinting, pen, stationery, plastic, yellowing
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.
Inspiration: 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. This ballpoint pen will age with the user through long use, and each piece will take on its own personality. This is a special ballpoint pen that contains the pleasure of nurturing for long usage.
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.
