If you frequently fill up your fountain pen with ink from ink bottles, you’ll know that a fountain pen converter is essential. Since you are refilling the ink regularly, there is a high risk of spilling the ink in this process. This can be quite a hassle. Worry not because we’ve compiled a list to help you find the best fountain pen converter for all your creative needs. 

These converters will not only help you to refill ink with ease but also can potentially prevent spills. We will look at converters from a wide variety of brands, including Parker, Waterman, and more. So, let’s dive in and take a look at some of the best fountain pen converters to help you fill ink faster.

1. Schmidt Universal Fountain Pen Ink Converter

Our first product, the Schmidt Universal pen ink converter can fit most European pens and it is quite durable. The best part is that it does not leak no matter how much you use it. On top of that, this product is compatible with a variety of pen brands. 

Due to its length and overall size, you can use the Schmidt Universal converter with almost any fountain pen. This is a basic, international converter that will work with most fountain pens you will see in stationary or online stores.

Unfortunately, the biggest downside to the Schmidt Universal is that it doesn’t work well with the popular fountain pen brands: Parker, Waterman, and Cross.

Before making your purchase, keep in mind that other than the pens mentioned above, this product rarely fits other fountain pens.

Buying Guide

Finding the perfect converter can feel impossible if you do not know what you’re looking for. There are so many options available in terms of materials, size, and brand. Below we’ve compiled a list of some of the most important factors to look out for when buying a converter for your fountain pen: 


This is the most important element to consider when looking for a fountain pen converter. If you get an inexpensive product made with cheap materials, chances are your purchase will break quickly and easily. This will force you to buy new converters and spend money you could have saved if you had bought a more robust product in the first place. To avoid this potentiality always make sure that the frame is durable so your converter will last with repeated use. 


Since fountain pen converters come in a variety of shapes and sizes, you need to make sure that you get the correct size for your pen. If you get the wrong size, you won’t be able to fit it on your pen and it would be a waste. However, there are some items that have a universal size. Try getting that as it will fit on almost any type of pen. When in doubt, contact the manufacturer so you can be sure you are purchasing the right converter for your pen.

Tips for How to Make the Most Out of the Product

Once you have purchased a pen converter, you will want to handle them with care to ensure that they last for a long time. One of the best things that you can do is to keep them safely stored so they do not take on damage or get misplaced. Some converters can be fragile so be sure to take extra care when refilling them with ink.

You should also regularly clean the fountain pen and converter in order to maintain its functionality and to prevent build-up and blockages. Having a lot of leftover ink can eventually cause a leak or damage the mechanism. This will make it harder for you to use your converter without damaging it.  


What brand is the best for fountain pen converters?

We’ve discussed the best brand in the next section in detail but the KOFUN is often considered the absolute best. Their converters are specifically made for all types of pens and they have tons of durability thanks to its metal construction.

Are all converters the same?

No, all converters are not the same. Most of the products are made for specific brands or certain styles of pens such as European or Chinese fountain pens. While there are universal converters, they can be a bit pricey and harder to find. 

Are all fountain pens refillable?

Yes, the beauty of fountain pens is that you can refill them and continue using them without any worries. Plus, if you use a converter, refilling your pen is an eco-friendly option that helps to reduce waste.
