Pentel Rollerball Gel pen 0,4 mm BLACK ballpen

With its low viscosity liquid gel ink, the EnerGel formula is quicker drying and smoother flowing than ordinary gel ink, giving a similar sensation to liquid ink. Because the ink dries quickly, it's appreciated by right and left-handed writers alike, as it produces smudge-free results on paper or hands. Unlike liquid ink products, though, EnerGel doesn't need a regulator to control its flow - the ink is delivered directly from the reservoir or refill to the tip in one smooth transition. That's why the family of EnerGel products gives you a good writing experience.
