We stock the official Montegrappa refills for all Montegrappa pens we stock. Ink cartridges are available in packs of 8 (in a standard international short size), as well as ink bottles in a variety of colours. The Extra and Monte_Grappa range feature an inbuilt piston filling mechanism and therefore not compatible with cartridges. Ballpoint pen refills are Parker style and available in a medium point. The Montegrappa rollerball refill is a euro format and available in blue and black ink.
