Monteverde are one of the longest established fountain pen manufacturers and these cartridges take advantage of all their experience.
The ink used includes Monteverde's ITF (Ink Treatment Formula) which drastically improves ink flow quality, lubricates and protects ink feeding systems from clogging, improves drying time on paper, and extends cap-off time.
Available in 11 colours to suit any requirement. Fits any Lamy fountain pen.
