What are the differences between the pen refills?The ballpoint pen refills have different stroke widths, which also impacts the writing feeling.
M approx. 0.4 – 0.5 mm B approx. 0.5 - 0.6 mm XB approx. 0.6 - 0.7 mm
The refill on my twist ballpoint pen no longer comes out, what can I do?If the ballpoint pen falls on its tip, the opening of the tip may be deformed, preventing the refill from coming out. Before sending your pen in to us for repair, you could try repairing it yourself.
Unscrew your twist ballpoint pen, insert the refill in the tip from the front in the opposite direction to the usual position and move it around in circular motions.
Then put the pen back together again. If the refill still does not come out, contact our customer service.
How do I insert a new refill?
On all refillable ballpoint pens, you can unscrew a section at the front - this may be the nib, the tip or the entire grip section:
How long will a pen write for?The writing life of a pen depends on various factors, like the type of ink or paste (gel pens have a shorter writing life than ballpoints pens for technical reasons, for example), the ball diameter and line width, the writing speed, the absorbency of the substrate, the temperature and humidity etc.
What is the advantage of a clutch pencil?
Compared with a wood-cased pencil, a clutch pencil has a constant pencil length, which means it always fits comfortably in the hand. The lead can write for much longer than the lead in a wood-cased pencil and can therefore almost be used in its entirety.
How do I refill leads on retractable or propelling pencils?To change the lead, pull the entire eraser unit from the shaft at the back. Insert between three and five leads in the opening created and mount the eraser unit again.
Now press or turn the push mechanism until the new lead has been transported through the pencil and is visible at the front again.
Propelling pencils from the e-motion and Ondoro series are filled as shown on the images.
Are there special fountain pens for left-handed writers?Our standard fountain pen is equally suited for left- and right-handed writers – and this is also what our users say in their feedback. Only school fountain pens come in different versions for right- and left-handed writers – e.g. Scribolino. The asymmetrical grip zone makes practising the correct grip easier for writing novices and enables fatigue-free writing.
Before purchasing a fountain pen, we recommend testing the different fountain pens at a specialist stationary retailer.
What nib thicknesses are available and how do they differ?The nibs differ in the stroke width and the associated writing feeling. The stroke width of a nib can not be measured precisely, as there are many influencing factors, such as the paper, the way the fountain pen is held, the writing method, ink output etc. Various nib thicknesses are available depending on the fountain pen.
The nib widths are outlined below:
EF (extra fine) = 0.45 – 0.55 mm
For a light handwriting, without pressure. Extremely fine writing style.
F (fine) = 0.60 - 0.70 mm
For small handwriting, with a low level of pressure. Fine writing style.
M (medium) = 0.80 - 0.90 mm
Suitable for all handwriting types. Medium-width stroke with normal writing pressure.
B (broad) = 1.00 - 1.10 mm
For large handwriting and signatures. Medium-width stroke with normal writing pressure.
I have chosen the wrong nib thickness, can I change it?To ensure that you enjoy maximum writing comfort, fountain pen nibs can be replaced with any of the available nib widths in the first three months from the date of purchase, providing the pen is free from damage and with proof of purchase.
How do I clean my fountain pen?We recommend cleaning the fountain pen regularly under running, clear and lukewarm water. Particularly if the ink has dried up through lack of use, when changing the ink colour or if the ink flow has reduced. With blue ink, the pen should be cleaned every three months, for coloured inks, cleaning should take place once a month, as these inks contain more colouring.
My fountain pen is having ink flow problems, what can I do?We recommend cleaning the fountain pen regularly (ideally every one to two months) under running, clear, lukewarm water. Particularly if the ink has dried up through lack of use, when changing the ink colour or if the ink flow has reduced.
If this does not improve the ink flow, contact our customer service at email@example.com
How do I insert a new cartridge?
To insert a cartridge in the fountain pen, unscrew the mouthpiece and press the cartridge into the mouthpiece with the opening. A spare cartridge stored in the shaft stabilizes the cartridge and prevents it from coming loose.
How do I fill a converter?
For the converter - after use - dip the tip of the nib in the ink and turn the converter clockwise on the end piece to fill the converter with ink. Then remove 2 drops of the ink by turning the converter anti-clockwise.
Can I use an ink other than the Faber-Castell ink?The quality of the ink (colourant content, surface tension etc.) is extremely important. This varies between the manufacturers. Some inks have an extremely low surface tension, for example. When these inks are used, fountain pens tend to leak. To guarantee an optimal ink flow, the ink and ink feed must be perfectly coordinated. This is also the reason why every fountain pen manufacturer recommends using their own inks. A problem-free ink flow can therefore only be guaranteed when Faber-Castell or Graf von Faber-Castell inks are used.
Which inks are indelible?The Graf-von-Faber-Castell inks in cartridges are identical to the inks from the glass pot. The following inks from the Graf von Faber-Castell line are indelible: Cobalt Blue, Carbon Black, Stone Grey, Moos Green, Midnight Blue, Violet Blue, Garnet Red, Hazelnut Brown, Deep Sea Green) The indelible property corresponds to ISO 12757-2 and is indicated on the packaging.
Is the ink harmless?We assure you that our inks are completely harmless to health.
What is thermosensitive ink?The uni-ball Signo TSI pens can be erased with the end of the cap. This is possible thanks to the thermosensitive ink. The ink is rendered colourless as a result of the heat generated by the friction, meaning it is removed and can be overwritten again right away.
And if you erased something by mistake, there’s another useful feature: Simply put the sheet with the writing you want to restore in the freezer. In time, the writing will become visible again.
