A Beginner’s Guide to Flexible Nib Fountain Pens

Flexible fountain pen nibs are trickier to use than ordinary pens. If you do not know how to control the pen you could feed too much or too little ink into your paper. This may destroy your work. Here are a few tips for beginners using flexible fountain pen nibs:

Tips for Beginners:

Ensure Your Pen is Always Clean

A flexible nib pen demands a high flow of ink. As such, there should be no blockage in the ink flow as that can lead to resistance when you are using the pen. 

You should use a damp cloth to clean the nib and cap of your pen to ensure there is no residual ink jammed up in there. Remember to only use lukewarm water to clean your pen. 

Keep Your Pen Filled

A flexible nib pen uses a lot more ink than a typical fountain pen. You should always keep your pen filled with ink to avoid running out of it while you are working. 

Check Your Angle

Angle is everything when it comes to using a fountain pen nib. The angle determines how much your nib flexes and how much ink is fed into the paper. You should hold the pen at an angle of 45 degrees to the paper and start making strokes. With practice, you will find the right angle that works for you. 

Beware, if the pen has a high angle it will not allow the nib to flex. If it has a lower angle than needed, you can end up releasing a lot more ink on the paper than you intend to. 

Choose the Right Ink

Ink with a wet flow works best with flexible nib pens as you want the ink to feed into the paper whenever you want it to. Higher saturated inks dry up and do not give you that smooth workflow you expect from this pen. Shimmery inks can also lead to railroading (a break in the flow). So, try and get the wet flow inks. 

Soft vs. Flex

People often confuse soft nib pens to be the same as flexible nib fountain pens whereas the truth is there is a very thin line that separates the two. Soft pens are more accurate and precise and there is only a small degree of line variation between the two.

Vintage vs. Modern

The vintage flexible nib fountain pens refer to the flex pens manufactured in the mid-1900s. If you ever have the chance to get your hands on one of these, do not miss it. 

The vintage flex pens have a different quality that makes them the best type of flexible nib fountain pens so far. Modern flex nibs are stiffer and need more pressure to operate than vintage flex nibs.


What to do if my flexible fountain pen’s ink is not flowing properly?

To avoid facing ink flow problems and when your pen’s ink flow is disrupted, clean your pen. You should clean the pen every other month using lukewarm water to prevent ink blockage.

How should I store my flexible fountain pen?

You should always store your pen horizontally and keep the cap closed so your nib does not dry out. Improper storage of the pen can also lead to the ink flow being messed up and the pen drying out.

Should I clean the ink converter when using different colored inks?

Yes, you should clean the ink converter before filling it up with a different colored ink. Otherwise, the remnants of the previous ink will get mixed with the new ink and the color of the pen’s writing will not be as you expected.

Can I travel with my flexible fountain pen?

Yes, you can travel with your fountain pen without worrying about it leaking. Due to the pressure changes in the cabin, the pen will leak. That is not the case in modern flexible nib fountain pens.
