AcroBall Pen contains an innovative hybrid ink for out-of-the-ordinary writing flow and smoothness as well as effortless, smear-proof performance. The ink writes smooth like gel, but dries quickly like a ballpoint. Retractable AcroBall is equipped with an ergonomic grip so that it can be held well in the hand and a tungsten carbide nib that cannot be deformed and will not wear out. Refillable ballpoint pen also features a 1.0mm point, black ink and silver barrel.
