Buying the correct pen refill can be tricky with so many options. The first step is to identify your writing type, particularly if you aren’t sure if it’s a ballpoint or rollerball. If you have a fountain pen, do you want to use cartridges or an ink converter? We recommend, where possible, choosing the same brand for your refill as your pen. If we don’t stock your brand, we offer a standard sized refill that can fit many pens. Some refills have options for different nib widths (e.g. fine to broad). Use our refill finder.
