The design of this beautiful ballpoint pen is based on hand-colored woodcuts of the Astronomicum Caesareum
, a Renaissance-era work that details the use of the astrolabe in calculating the altitude of stars. Now, you can hold the secrets of the astronomers right in your hand with this pen.
A twist mechanism is used to extend and retract the pen, which contains black ink. The pen accepts standard ballpoint refills such as the Schmidt P900 or Parker Golden Touch.
Proceeds from sales support The Metropolitan Museum of Art.
