Monteverde Canyon Rust from Monteverde's standard collection is a medium, warm brown fountain pen ink with medium shading and a pop of black sheen in large swabs. It dries in 20 seconds in a medium nib on Rhodia paper and has a 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.
