The easiest way to find the right cartridge or refill for your pen, is to start with the brand. Many brands have their own standard when manufacturing their pens, and therefore also their own cartridges or refills. So it is not as complicated as it may seem. In this guide, we list the brands and which cartridges or refills fit each pen. Simply find your brand and you will quickly see what works. If your brand is not listed, or if you are still unsure, you are very welcome to contact our customer service team. They will help you find the right cartridge or refill, without any hassle.
Fisher Space Pen
With FSP, it is simple, as their range consists exclusively of ballpoint pens, and there is one refill that fits all models.
- Pressurised refill for Space Pen & Parker: Fits all pens from Fisher Space Pen, except for the Q4 model which is not available at Pen Store. So whether you have a Bullet, AG7 or perhaps a Cap-O-Matic, you can be confident that the same refill applies. It also fits all ballpoint pens from Parker and pens from other brands that use Parker’s standard refill size, provided that the small adapter included is used.
LAMY
Lamy uses different cartridges and refills depending on pen type and model. Here you can quickly see which cartridge or refill fits your pen.
Fountain Pens
- T 10 Fountain pen refills: Used in all Lamy fountain pens, except Lamy 2000 which uses neither cartridge nor converter.
- Z 28 Converter: For the models AL-star, Joy, Nexx, Nexx M, Safari, LX and Vista.
- Z 27 Converter: For the models Logo, Studio, Linea, Accent, Dialog 3, Aion and CP 1.

Rollerball
Parker
If you have a pen from Parker, it is very easy to find the right one. There is only one ballpoint refill, one rollerball refill, one ink cartridge and one converter.
Fountain Pens
- Fountain pen refills: Used in all Parker fountain pens, such as IM and Duofold.
- Parker Converter: Also fits all of their fountain pens.
Ballpoint Pens
- QuinkFlow Ballpoint Refill: Used in all Parker ballpoint pens, such as Jotter and Jotter XL. Several other brands use the Parker ballpoint refill size as a standard in their ballpoint pens. One example is Rotring, which uses a Parker-style ballpoint refill and is therefore compatible with Parker refills.
- Gel Ballpoint Refill: An alternative to the refill above, in the same size. It can be used if you want a smoother, more free-flowing ink in your ballpoint pen.
Rollerball
- Quink Rollerball Refill: Used in all Parker rollerball pens, such as IM and Sonnet.
Pilot
- IC-50 Namiki/Pilot & Iroshizuku cartridges: Both cartridges fit, among others, Falcon, Capless and Justus. The only exception is Pilot MR (Retro Pop and Animal). This fountain pen only takes cartridges in the international standard size, more about this further down the page.
Platinum
All fountain pens from Platinum use the same cartridge and converter, but they are available in two different pack sizes.
- Fountain pen Cartridge 10 pcs: - Fits all Platinum fountain pens, such as #3776 Century, Preppy, Plaisir, Curidas and Procyon.
- Fountain pen Cartridge 2 pcs: - The same cartridge as above, but in a smaller pack.
- Converter
Platinum also offers cartridges containing Carbon Ink, a pigment ink. When using Carbon Ink, it is very important to clean your pen thoroughly, otherwise the ink can dry out and damage your pen.
Other refills to be aware of
Multi Pens
If you have a multi pen, that is, a pen with several ink refills inside, it is most likely refillable with D1 standard refills. D1 refills have the same length and thickness regardless of brand and are used in multi pens from Rotring, Lamy and Platinum. Here we have gathered a selection of D1 refills.
International standard size, what is it?
This standard is used by several different brands, which means you can combine one brand’s ink cartridges with another brand’s fountain pen. For example, Herbin’s Fountain Pen Refills Standard, Waterman’s Fountain Pen Refills and Caran d’Ache Chromatics use this standard size and therefore fit pens such as the Pilot MR, TWSBI Swipe and Waterman fountain pens.
Not found what you are looking for?
There are of course many other refillable pens in our range, and refills for them, that we did not have space to include in this guide. If you did not find your pen above, or if you still have questions about which refill fits your pen, you are always very welcome to contact our customer service, and we will help you find the right one.
