Is an Eyedropper Fountain Pen Worth it? Reviews on Top 5
eyedropper fountain pen

Pen aficionados and fountain pen users worldwide obsess over eyedropper fountain pens mainly for their mess-free ink writing experience. The conversion can be difficult to master for beginners –  but not impossible.

In this guide, we break down the advantages and disadvantages of using an eyedropper fountain pen, suggest ways to fill it up, show how to prevent leakage, and review the top five eyedropper fountain pens.

What is an Eyedropper Fountain Pen?

An eyedropper fountain pen is a traditional fountain pen but instead of an ink filling mechanism built in, it is inked up like a pipette through the nib. There are two types of eyedropper fountain pens: the Japanese kind and the cartridge-converter kind. 

Here’s a detailed description of each:

Japanese Eyedropper Pens

Found mostly in higher-end fountain pens, a Japanese-style eyedropper pen is crafted with a valve inside the barrel for ink storage. It is best known for its o-ring mechanism that works like a piston when the pen is closed so there are no leaks.

When writing with a Japanese-style eyedropper fountain pen, the valve needs to be opened for a consistent ink flow to the nib. It should not leak or even ‘burp’ ink. Such eyedropper pens are a favorite among fountain pen aficionados that like to enjoy the real deal instead of ‘hacking’ into an original fountain pen.

Cartridge-Converter Eyedropper Pens

A modern take on eyedropper pens, the cartridge-converter style is cooler and more efficient. Unlike Japanese-style eyedropper fountain pens, the cartridge-converter eyedropper pen does not come with a valve. Instead, it is sealed so that the barrel of the fountain pen is used as an ink reservoir.

Cartridge-converter eyedropper fountain pens usually have a transparent body so one can see the ink sloshing around. They also tend to have a variety of ‘colored’ barrels with multiple tones of ink. These pens are more beginner-friendly and cost-efficient so that everyone can enjoy them regardless of expertise.

Advantages and Disadvantages of Eyedropper Fountain Pens

Before you decide on an eyedropper fountain pen, let’s discuss the pros and cons of writing with one. As easy as it is to use, there are a few drawbacks that need to be kept in mind. Fortunately, they aren’t dealbreakers. 


One of the main benefits of having or converting a fountain pen into an eyedropper pen is that it is simple to use. Yes, the conversion may be a feat for experts but once you get the hang of it, it’s as easy as using a traditional fountain pen.

Most eyedropper fountain pens can hold up to five milliliters of ink and the body lasts a lifetime, which is why they are worth the effort, time, and money. In the grand scheme of things, eyedropper fountain pens are quite cost-effective. 

Regardless of whether you’re a student writing notes all day or a professional signing business deals, the eyedropper fountain pen is a great instrument.


The only drawback of an eyedropper fountain pen is that it can be high-maintenance. If it’s not properly maintained, it could leak. Since the ink reservoir holds a large capacity in nothing but the barrel, the leakage can produce large ‘burps’ of ink.

In addition, the cleaning procedure is quite involved, especially when changing the colors of ink, which can be rather time-consuming. But the end result is rewarding because it can last up to two weeks, or more, depending upon how much you write.

Steps to Fill an Eyedropper Fountain Pen When Converting

Before converting your fountain pen to an eyedropper, it is crucial to clean it from top to bottom. 

First, flush out the ink if it has a converter built in, and then fill it with water to flush it again and clean out any residual ink. Use clean tepid water with a mild detergent since hard water and soap crystals can block the nib reservoir and stop ink flow.

When it’s dry, it is ready to be converted to an eyedropper. Here’s what you’ll need:

  • Ink syringe or pipette
  • Silicon grease or o-rings
  • Paper towel

Once you’ve gathered the ingredients, the next steps are easy: 

  • Dismantle the fountain pen by removing the nib section and grip from the body or barrel.
  • Make sure the ink filling mechanism (cartridge or converter) is removed.
  • On your finger, take a tiny bit of silicone grease. You can also use a Q-tip, just make sure it isn’t soaking in the grease.
  • Spread the silicone grease around the split halves of the section and body, also known as the threads.
  • Select your ink and fill the barrel up, making sure it reaches the threads but does not overflow.
  • Reattach the fountain pen grip section to the barrel or the body.
  • Allow the pen to rest until the ink flows to the feed consistently. If you need to use it right away, simply tap it down gently on a table so the ink works through the feed easily. 

How to Prevent a Burping Eyedropper Fountain Pen

Burping refers to large ink blots that leak out of the grip section of the fountain pen. It is particularly prevalent in eyedropper fountain pens but fortunately, it can be avoided by following a few simple procedures. 

Here are the necessary steps to take to prevent a burping eyedropper fountain pen:

Use Silicon Grease and O-Rings

The best way to enjoy a converted eyedropper pen is to spread a bit of silicone grease around the threads or between the grip section and the body. This essentially seals in the ink and prevents it from traveling up to the threads and burping out. 

If your budget allows, you can get an o-ring to place around the threads to ensure there is no leakage. An o-ring is present in professionally manufactured eyedropper fountain pens which guarantee there’d be no leak.

Travel with a Fully-Inked Pen

Changing altitudes can be the arch nemesis of an ink pen – especially one with a large ink capacity like an eyedropper fountain pen. When traveling by air or road, make sure the barrel is filled up with ink.

Unlike traditional fountain pens, the ink should be filled to the brim of the barrel eliminating any air pockets that would otherwise expand with changing pressure and temperature. 

Store it ‘Write’ Side Up

This is one of the most important steps of using an eyedropper fountain pen. When resting for a break or capping it up for later use, make sure to store the fountain pen with the nib facing up. This way the ink won’t be able to burp out unless there is a sudden change in temperature or pressure.

Make sure it is always capped so the majority of the ink can be contained in case of a leak. It isn’t generally recommended to clip an eyedropper pen since accidental falls can break the nib and splat large amounts of ink everywhere. Instead, store it in a pen case when traveling.
