- Ink refills for Platinum Preppy and Plasir Fountain Pens
- Quantity - 2 cartridges / pack
- Please note the blue/black ink is an iron gall ink. If left unused in a fountain pen for extended periods of time this can corrode steel nibs. On the plus side, iron gall ink is permanent, semi-waterproof, and darkens over time, provided the pen is regularly used or cleaned out with water when not in use there will be no issues.
