A rollerball pen designed for scientific minds. Curiosity and persistent research lead to revolutionary discoveries. Dmitri Mendeleev, Russian chemist and inventor, is known for formulating the Periodic Law and drafting a version of the Periodic Table of elements. This capless rollerball pen was inspired by the innovative Dmitri and his commitment to science, featuring the Periodic Table on a metal barrel, set off by chrome trim. The pen is packaged in a patterned tube, additionally illustrating all the scientific elements. The precise writing apparatus features Retro 51’s signature knurled twist top and can effortlessly convert to a ballpoint pen with a refill change.
