Which inks are permanent or waterproof?

Most fountain pen inks are far from permanent simply because there is no reason for them to be. However, sometimes the writer needs a permanent and/or waterproof ink. This page shows a list of such inks that we stock.

Please refer to individual product descriptions for more information.

A note on using waterproof or water-resistant fountain pen inks for drawing:
Many artists and illustrators like to use a fountain pen to create an outline over which a colour wash is applied. Fountain pen inks are not really designed with this level of water resistance so you may experience some colour being shed when the wash is applied over the ink. The amount of ink shed is dependent upon the brand of ink and the type of paper used. Therefore, it's allays best to experiment first.

Top tip:
If you want to address an envelope using non-permanent fountain pen ink and you are concerned about what would happen if it gets wet during delivery, rub some candle wax over your writing. This will add a protective layer to stop the ink running if it gets rained on.
