This pen is a refillable capped rollerball made using parts of a clock. It sports a clock face on the cap and clock pieces on the body. Due to the cap, this is a heavier pen weighing in at 1.8 oz. The cap is Not postable, which means it will Not twist onto the end of the pen. The accents on this pen are rhodium black titanium. All of our pens come with a free black ink refill. We offer two different ink colors: blue and purple. If you would prefer a different color ink, please send us a message, and we will be happy to change out the original ink for your color of choice. When it's time to replace the rollerball refill (see photo for details), turn the bottom counterclockwise. There is a spring inside the top, so be careful not to lose it.
