Monteverde Monteverde Green from Monteverde's standard collection is a dark forest green fountain pen ink with medium shading and low red sheen. It dries in 20 seconds in a medium nib on Rhodia paper and has a slightly wet flow. Monteverde inks feature ITF, which drastically improves ink-flow quality, extends cap-off time, and lubricates and protects the ink feeding systems from corrosion and clogging.
