Platinum Cartridges - Blue/Black

Product Description
Maximum quantity available reached.

This blue-black iron gall ink is fairly waterproof and has good archival qualities, but it is also more acidic than normal fountain pen inks. These cartridges are safe to use in any fountain pen, but it is recommended you clean your fountain pen regularly (every 4 weeks or so) to avoid corrosion, especially in pens with steel nibs.

Each box contains 10 cartridges.
