The Energel liquid gel pen is an executive, metal-bodied capped pen. The light weight pen of 17.2 grams only is designed for comfortable writing and comes with Blue & Black  Energel ink inside, which has been internally tested and proven to write more smoothly than the leading brand. Energel liquid gel ink dries so fast even left-handed writers love it - no smears, no smudges and no globs. The 0. 5mm tip writes smooth, medium lines. Energel pens are refillable with any size/color energel ink refill.
