Waterproof Fountain Pen Inks

(47 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.
