Herbin - Cleaning Solution for fountain pens (tin of 6 cartridges)

A fast and easy solution that works for every fountain pen ...

J. Herbin fountain pen cleaning solution supplied as a tin of 6 cartridges. Suitable for any pens that use standard international cartridges.

To use, simply pop one of these international standard size cartridges in your pen and do some writing until clear liquid is passing through the feed, leave for a few minutes, repeat and then rinse with cold water. Follow up by flushing through with water - either use a converter, or use the now empty cleaning cartridge again.
