Yes, Rollerball and Fineliner refills are interchangeable. Please note that LeGrand size refills cannot be used in writing instruments that are suitable for the standard size and vice versa.
No Rollerball and Fineliner refills cannot be used in a ballpoint pen and vice versa.

The Ballpoint refill uses ink paste and one can use a certain amount of pressure while writing. Therefore ballpoint refills are perfect for filling forms with multiple pages and for writers who write a lot. Our ballpoint pens have a twist mechanism, which protrudes and retracts the refill.

The Rollerball uses liquid ink, similar to fountain pen ink. The majority of our Rollerballs have a cap, which you need to take off before writing. Closing the cap ensures that the ink does not dry up. There are only a few which do not have a cap, e.g. the Rollerball Capless which uses the special "capless refill".

This depends on the writing system and the model you have. Should you have a vintage Rollerball or cartridge Fountain pen you can use our current standard size Rollerball refills or ink cartridges as the measures of these refills have never changed. Should you have a Ballpoint, please contact us including clear pictures of the writing instrument and the old refill, if available, so we can suggest the appropriate refill for you.

Montblanc offers an exclusive selection of different Montblanc ink colours. In order to best protect your Montblanc fountain pen from any damage, please only use Montblanc ink.
