Bullet antimicrobial raw brass Space Pen

The features of this pen reach new spheres! The antimicrobial pen works on water and grease, from -45 degree frost to +250 degree heat, upside down, and even in a weightless state. Over time, each pen will develop a unique patina as it responds to the environment, your body chemistry, and the way you handle the pen. It can always be polished to restore its original look. Size of the pen: opened 13,5 cm and closed 9,5 cm.
