Three ink colors in one pen, switched with a twist of the barrel. The Uni-ball One Multi Pen uses pigment-based gel ink formulated with larger particles that sit on the surface of the paper rather than absorbing into it, so dark inks read darker and bright inks read brighter. At 0.38 mm, the line is fine enough for tight margins and small script without sacrificing visibility. The barrel diameter is wider than a standard pen, making it comfortable to hold over long writing sessions. A spring-loaded metal clip attaches securely to a notebook cover, planner pocket, or bag strap, so it stays where you put it. The ink dries quickly and resists bleeding, keeping entries clean across most paper weights.
