Pen Refills and Accessories
Ran out of ink, or just fancy a change of colour? Here at The Online Pen Company we have a wide range of pen refills and accessories to get you back up and writing in your favourite colour. Choose from a huge selection of colours, fitments and grades of refills including ink bottles, cartridges, converters, erasers, pencil leads and your standard replacement ballpoint pen refills and rollerball pen refills. We even sell leather pen pouches, to keep your pen safe and secure from everyday wear.
There are various different types of pen refill, which we touch on more at the bottom of the page, but to start with, you need to know what pen you have, and then look for the specific pen refills to match it. For example a ballpoint pen refill won’t fit a rollerball pen, and some ink cartridges won’t fit into all fountain pens. The individual product pages should have more information on which pens they fit. If you are really unsure then feel free to get in touch with us, and we will be more than happy to help.
For an easy starting point, try visiting the refill brands section and looking at the pen refills for the specific brand of pen that you have.
Types of pen refills
Ballpoint pen refills
A ballpoint pen is a capless, often click action pen where the refill is constantly exposed to air to prevent it drying up. Therefore all ballpoint pen refills have oil based ink, which does not dry up on contact with air. Some pens have a different fitment for these refills so be sure to check the picture or ask advice, but there is one size that a lot of manufacturers have adopted which is the one found in Parker pens.
Rollerball pen refills
Rollerball pen refills are different to the ballpoint ones above because a rollerball is a capped pen, meaning there is an airtight seal. This allows the ink to be water based, and much similar to the writing feel and style of a fountain pen. Fitting is quite specific to the pen that you have with these, so be sure to check the picture against your own to make sure it’s the right one, as always we are happy to answer any questions you may have.
A fountain pen does not take a ‘refill’ in the sense of the above two pens, because it operates through a gravity fed nib, so all that is required is a ‘cartridge’ of ink to connect to the nib assembly. There is an ‘International’ size which is mainly used by European and far eastern pen manufacturers, which opens you up to the possibility of inks from other manufacturers like Diamine, who have a huge selection of all different colours. Make sure you check thoroughly before ordering what cartridge your pen takes.
Fountain pen converters are small vacuum devices that fit into a pen that is made to accept cartridges, but they allow you to use bottled ink. They are essentially a refillable ink cartridge, where you use the piston to create a vacuum to suck the ink up into the converter. The fitting for these is fairly manufacturer specific, so be sure to check you are getting the right one.
Bottled ink in a wide range of colours from lots of different manufacturers, however they can all in theory be used interchangeably, so its just a case of choosing which one you like the most.
Mechanical pencil leads are very small sticks of lead that can be put into a mechanical pencil, when the old lead is worn or damaged, because obviously you cannot sharpen a mechanical pencil in the way you would with a traditional one.
Some mechanical pencils have space for an eraser in one end, and you can get replacements for these too. Simply swap the new for the old, however make sure you have the right fitment.
Multipen refills are replacemtn refills to suit multipens, so due to the technology differing in all multipens, these are quite a specific fitment to the individual pen.
Parker 5th Refills
Parker 5th is a completely new writing system, outside of any conventional category, so they take their own specific refills which can only be used in pens encompassing that technology.
