The Albert (Einstein) pen from Retro51 features a metal barrel full of mathematical equations, with a "stonewashed" metal trim.
This pen would make the perfect gift for the mathematician or physicist in your life. Retro 51 pens are loved for their perfect weight and balance, and the smooth-flowing line of the rollerball ink cartridge. If a ballpoint is preferred, no problem - you can interchange the Retro 51 refills as desired.
Includes one black rollerball ink cartridge (REF5P-B), but can be converted to ballpoint (REF71/77-B.)
