The Best Ink For Flex Nib

Fountain Pen Inks

Choosing the right ink for your fountain pen can be intimidating, especially if you’re a lefty or new to flex pens. However, having the right ink can make all the difference when using this type of pen. If you’re just beginning to explore using flex pens, buying inks online can be an even more confusing process. But fret not, we guide you here so you can easily understand what to get!


Fountain pen inks are not only different in colors, but also in type. Some are water-based, while others are pigment-based. Each of these ink types has its own unique characteristics that can affect your writing experience.


It is important to choose the right pen ink for your flex pen. The best fountain pen inks are those which offer a wet flow to create extra line variation in flex pens. For this reason, I would caution against using any sheeny, highly saturated, or shimmery inks when filling your flex pen for the first time. This can lead to skipping or railroading in your pen.


Flow refers to how quickly one feels the ink in a pen moving on the paper. The wetter an ink, the faster it moves on paper and the more ink it deposits into the space between the pen tip and the paper. In general, wet inks are smoother than dry inks, but dry inks are less likely to feather or bleed through average-quality paper. That’s why quality papers are another key important factor that we will talk about next time.


These are our recommended inks for flex pens:
