Xpress Fineliner features a 0.8mm, fiber tip point for expressive and striking writing performance. Fiber tip also glides extremely gently and is stabilized with a stainless steel tube that enables you to work with a ruler and template. Cap-off ink does not run dry even if the cap is removed for two to three days. Water-based ink is suitable for documentary use. Ergonomically shaped, generously rubberized barrel promotes tireless and relaxed writing without hand fatigue. Cap has a sturdy metal clip and fits neatly on either end of the pen.
