Dirt and grease in the atmosphere and on your hands mean that your pen will become dirty over a period of time. A build up of grease on the nib and feeder may also prevent the ink from flowing properly. That’s why we recommend cleaning your fountain pen three or four times a year. To keep the ink flowing simply flush out the filler mechanism, nib and feeder system with tepid water until the liquid runs clear, then dry gently. Holding a lint free cloth against the nib slit will help draw excess water out of the feeder system. Do not use detergents, solvents or hot water as this may damage the mechanism or finish. Do not put the whole pen under water as this will damage some filler mechanisms.

This is a very personal thing and should simply be at a comfortable angle for your writing style. Ideally the nib should receive even pressure on each half to avoid the risk of splitting the nib. Over a short period of time the malleable properties of the nib will allow it to contour to your writing style.


As the nib will be personalised by your handwriting it is best used only by one person. If you wish to gift your pen to someone we recommend you have a new nib fitted.

All Conway Stewart writing instruments are designed to give you a high quality writing experience for many years. Each pen is supplied with a comprehensive User Guide that explains how to look after your pen, and how to fill it with ink. If you have any further questions about your pen, please contact us.

We recommend that you use only quality inks, such as those available to purchase from our Accessories page, to ensure a quality writing experience. We recommend the use of ink that is less than a year old as residues may become a problem with inks that have been stored for lengthy periods.

Left-handed writers use so many different writing styles; overwriting and underwriting, writing uphill, writing horizontally, and writing downhill, that it’s not really possible to recommend any one nib. Experimentation on what works for you is the only answer!

Please see attached diagram.

Round Nibs: A round nib is ground and polished to have roughly a circular footprint, so that its line width is fairly uniform no matter what direction the nib is moving across the paper. Here is a magnified silhouette representing the basic shape of a round nib, together with a cross illustrating the uniform stroke width that this nib produces. All of our standard nibs are Round Nibs.



Stub Nibs:A stub nib is elongated sideways, to have a footprint that is somewhat elliptical. This makes it lay down a slightly broader line when moving up and down (in relation to the nib itself) and a narrower one when moving sideways (again, in relation to the nib). The wider line is between 1.5 – 2.5 times thicker than the thinner line in our custom ground stub nib. The eccentricity of the ellipse isn’t too pronounced, and the nib is still polished to have nice rounded edges. This means that you can write with a stub just about as easily as with a standard nib. Here is a magnified silhouette representing the basic shape of a stub nib, together with a cross illustrating the slight variation in stroke width that this nib produces.



Italic Nibs:

An italic nib is far more elongated. This makes the difference between its broad (up-and-down) strokes and its narrow strokes (sideways) more pronounced than with a stub.A traditional italic nib has a perceptible straight edge across the tip, and relatively less rounding to the edges than a stub nib. This results in a greater tendency to catch on corners and to skip if the nib is not held straight-on to the paper. This can make the nib feel “scratchy”. However, there is a compromise grind called cursive italic, which has more rounded edges than a traditional italic. When properly ground and finished, a cursive italic nib can produce stroke variation almost as strong as an italic nib while the writing feel is nearly as smooth as a stub of similar width. All our custom ground italic nibs are cursive italics unless otherwise requested.

See diagram here.

The approximate line widths produced by these nibs are as follows:

- Broad 0.85 – 1.00mm
- Medium 0.65 – 0.80mm
- Fine 0.45 – 0.60mm
- Extra Fine 0.35 – 0.40mm

These are approximations only and will be influenced by the amount of pressure exerted by the writer and the type of ink and paper being used.

A rollerball is like a biro/ballpoint but has the free-flowing ink qualities of a fountain pen. Beautiful to write with, yet with the convenience of a ball-point.

Calligraphy nibs have the same shape as italic nibs (i.e. elongated), but might be even wider, and are finished with squarer edges. This square-edged grind and the wider footprint result in a greater tendency to catch on corners and a greater tendency to skip if the nib isn’t held straight-on to the paper (i.e. when one side of the nib lifts away due to the nib’s being rocked sideways). Writing too rapidly with a calligraphy nib tends to produce scratchiness and skips. However, by writing more slowly, calligraphy nibs give a very crisp and controllable line width, and with practice, some writers become very proficient with calligraphy nibs, producing beautiful text. We can grind specialist calligraphy nibs on request.

An oblique is ground so that the writing tip contacts the paper properly when the pen is rotated in the user’s hand. This suits some handwriting better. There is some confusion over what is a left oblique, and right oblique, so a good way to remember it is as follows.

Size 6 and size 5 nibs primarily differ in their dimensions, with size 6 nibs being larger and found on larger pen models, while size 5 nibs are used in smaller pen models such as the Collectors, Silvicity, and Series 58 pens.

These nib sizes are not interchangeable due to their specific design for the respective pen dimensions. Both sizes offer various nib options, such as extra fine, fine, medium, and broad, although availability may vary depending on the pen model and brand.

The writing experience and ink flow can also slightly differ between the two sizes due to the differences in nib size and design.

The cleaning and maintenance process is generally similar for both sizes, but it is essential to follow the manufacturer's recommendations for each specific pen model to ensure optimal performance and longevity.

Here is an image showing the comparison of a Size 6 nib on the left and Size 5 nib on the right.

Conway Stewart used 2 different formats for the numbers engraved on the barrel.

If it was a Limited Edition pen, then the number was the Edition Number ie 10/300 means this was the 10th pen made in a limited edition of 300 pens.

However, much more commonly used was the format in the below photo which shows a strange number 058/001. The first number is the colour reference of the pen and the second number was the serial number. In this example 058 = Classic Black and 001 = this is the first pen made in that colour in that range.

The full list of colour numbers and their correlating pens can be found here.

When carrying your pen do so in an upright position to avoid ink leaking from the nib. This is relatively straightforward in jacket pockets and briefcases but attention needs to be paid to the pen’s position in purses and handbags. The nib should be pointing up – this will help ink flow back into the reservoir and reduce drying and clogging of ink residues at the nib.

Air Travel
When travelling by air your fountain pen should be fully filled or alternatively emptied and flushed clean before travel. If the pen reservoir is only partly filled the air in it may expand or contract resulting in ink seepage. Always keep a filled pen upright when travelling by air.

1. Drain your Conway Stewart pens before storing them for a long period of time without use by holding the pen over a sink and turning the euro-converter knob anti-clockwise to purge the ink.

It can take up to 28 days for your new pen to be completely assembled.

Production of the pens can take up to 28 days.

For shipping we use a variety of premium carriers to ensure our products arrive safely to you. Generally, shipping takes between 2 - 7 days.

If you are unsure about a pen at first sight, please just dip test it first using washable blue ink, just as you would do in a traditional shop. We reserve the right to reduce the amount of a refund if a pen has been mishandled.
