Waterproof Fountain Pen Inks

(54 products)

If you are looking for an ink to sketch and use for watercolour washes, please look at the De Atramentis Document ink range. Some of the other inks will not be suitable for this.

We have a range of fountain pen inks designed for use in pens which are waterproof to differing levels - some are permanent and will resist UV light and bleach, some will fade a little in water but will stay readable and some will stay put completely, even in a monsoon!

Read the individual ink pages for more information and you can also watch our YouTube video showing the infamous Noodler's Baystate Blue and how it reacts in water.
