Here are answers to some of the most common questions we get asked about fountain pens and ink. If there is something we have not covered, get in touch and we will be happy to help.
My pen won't write. What can I do?
If it is a brand new pen, make sure the cartridge or converter is pushed in fully. An ink cartridge has a seal that must be broken for ink to flow, and it can take a little time for the ink to work through the feed to the nib. Try gently squeezing the cartridge to push some ink into the feed, or twist the converter to draw ink up. If the pen still will not write, flush it through with water using a bulb syringe to clear any dried ink or debris.
How do I clean my pen?
It is best to clean your pen thoroughly with each ink change. Disassemble the pen and flush it with tap water -- or a dedicated fountain pen cleaner for more stubborn stains. Fill a bulb syringe with water, insert it where the cartridge or converter sits, and gently expel water through the nib until it runs clear.
What is the difference between a cartridge and a converter?
A cartridge is a pre-filled, disposable ink reservoir. A converter is a refillable reservoir that sits in the same position, allowing you to use any bottled ink. Converters give you a far wider choice of colours, are more economical in the long run, and produce significantly less plastic waste.
Which cartridges or converter will fit my pen?
Some pens take a standard international cartridge or converter; others require a brand-specific type. See our fitting guide to find out which your pen needs. For example, a Caran d'Ache takes an international standard type, so a Pelikan international standard converter will also fit.
Which ink is best for my pen?
Most standard fountain pen inks -- such as Diamine or Parker -- are suitable for all fountain pens. If your pen brand also produces its own ink, that is always a safe choice. Shimmer inks are generally compatible with most pens but should be cleaned out after use to prevent clogging. Avoid highly pigmented calligraphy inks intended for dip pens only. Noodler's Baystate Blue is waterproof but notorious for staining, so it is best kept to a dedicated pen.
What is iron gall ink?
Iron gall ink is made from iron salts and tannic acids and was the dominant ink from the 5th century onwards. Traditional formulations are acidic and can wear down nibs over time. Modern iron gall inks are far less corrosive and are safe for use in fountain pens, though they should be cleaned out after use. Iron gall ink is waterproof, making it ideal for official documents.

Can I travel with my fountain pens?
Yes -- with a few simple precautions. Fill your pen completely or empty it entirely before flying to eliminate the air bubble that causes pressure-related leaks. Always carry pens in hand luggage, nib-up. Read our full guide to travelling with fountain pens.
I am new to fountain pens. Which one should I choose?
There is a wide range of excellent entry-level fountain pens available. Good starting points include pens from Kaweco, Pilot, TWSBI, and Platinum. Read our guide to the best fountain pens for beginners for a full breakdown.
Which nib width should I choose?
Extra Fine: a very thin line, good for small handwriting. Can feel slightly scratchy due to the small nib tip.
Fine: a popular choice for smaller handwriting and everyday writing.
Medium: the most common nib width, often the default option on many pens.
Broad: a thicker stroke that shows off sheen and shimmer properties in ink particularly well. Best used with good quality fountain pen paper.
Stub/1.1mm: produces a varied line width due to the nib shape -- ideal for signatures, greetings cards, and calligraphy.
Which paper should I use with my fountain pen?
You can write on most paper, but to get the best from your pen and ink, choose a feather-resistant paper of 80gsm or above. Standard copy paper will cause ink to bleed and spread. Good fountain pen paper lets the ink sit cleanly on the surface, showing off colour, shading, and sheen to best effect. Rhodia produce an excellent and affordable range.
