Faber-Castell Ink Converter for Fountain Pens

Easy fill, quality-engineered. Should last a lifetime!

My go to cartridge. Fits the majority of my pens and never had one fail, Plenty of space for ink in the cartridge. I like the quality of Faber-Castell in general, so an easy pick for me

Bought this item as a few reviews said it fitted the Mont Blanc Starwalker fountain pen. Nothing wrong with the product itself, but it definitely does not fit my Starwalker pen (about 2 years old). Difficult to rate the product as I cannot use it, but I am fairly sure it does what it is supposed to do, just not on my pen!

An excellent product - purchased for my Montblanc Starwalker and fits perfectly. It fills correctly and is better than most converters. All in all, a no frills converter that does the job perfectly. The service was absolutely top-notch! The seller sent the item first class and it arrived next day - absolutely terrific value for free postage! Couldn't have asked for more.

This is much better than some cheaper alternatives with narrow opening that I used. They fit snugly but are not so tight that you would need to heat them first. They are also designed to maximise the volume inside the chamber and hold more ink than others.

Easy to use converter for fountain pens. Looks authentic and original, and it works as described. I have used it in a couple of fountain pens, and no leak so far. You just need to remember to insert it properly, and purge it a couple of times when refilling it to make sure you get rid of any air bubbles. Overall, very satisfied with my purchase.

I had an oldish fountain pen that I was fond of - this fits ok so I am very pleased. Fairly easy to use. Glad I bought it and it's not exactly expensive so no complaints

Firstly its of good quality and I would not hesitate to recommend in most circumstances, especially for Faber Castell pens however.... I got the impression from the description this would fit any "standard" fountain pen, however due to the diameter of the turn handle (which is quite thick) it does not fit my Waterman Expert pen as the barrel is too narrow to accommodate the size of the converter. Probably my fault in trying to save a couple of pounds compared to the Waterman version, but be aware.

Fits my Schneider voice pens really well. Great quality. Will buy again if needed.

The ink capacity is great and is able to hold a fairly good amount of ink. I must praise the twist knob as for somebody with sweaty fingers I still find twisting it to be really easy and very smooth! When placing it onto the pen not only does it look sleek it also fits very snugly and tightly inside. I would very likely purchase this again for my other pens as it's such a great converter.

Works perfectly with my Muji aluminium fountain pen - so excited to not use cartridges anymore !

Great converter. Smooth screw and easy to use, holds a lot of ink and is well worth the price. A great product overall.

I used to refill non-refillable cartridges with a needle, which worked OK but sometimes the cartridges would leak, making a mess. I guess it is because they aren't really meant to be reused indefinitely. Anyhow, I've been using this refillable converter for a while now and it works just as advertised. I go through a lot of ink because of my job - my Faber-Castell Ambition pen is my daily driver. Even the refilling process is less messy than my old system. For the price, I highly recommend it.
