This budget-friendly retractable fountain pen is perfect for taking notes wherever you go. The nib extends and retracts with the push of a button, and an airtight trapdoor protects the nib from dry out when retracted. The pen comes with a pack of five blue ink cartridges, plus an empty spacer cartridge pre-installed. Though the packaging says "Erasable Blue," this just means that the blue is washable.

Note: This pen is not compatible with standard international cartridges. Compatible cartridges can be found under Recommended Refills/Parts.
