With its revolutionary low viscosity liquid gel ink, the EnerGel formula is smoother flowing and quicker drying than ordinary gel ink, giving a similar sensation to liquid ink.
Because the ink dries quickly it‚¬„¢s especially appreciated by left-handed writers, as well as those who are right-handed, as there‚¬„¢s less risk of the ink being smudged when your hand moves across the page. Unlike liquid ink products, though, EnerGel doesn‚¬„¢t need a regulator to control its flow ‚¬€œ the ink is delivered directly from the reservoir or refill to the tip in one smooth transition giving you the ultimate writing experience!
