Sun-Star Tank Large Capacity Gel Pen – 0.5 mm

Say goodbye to running out mid-note. The Sun‑Star Tank Large Capacity Gel Pen is built to go the distance: its entire barrel functions as an ink reservoir, offering many times the ink volume of standard gel pens. Designed for heavy writers, professionals, and those who write often, it delivers extended writing sessions without frequent refills.

With a fine 0.5 mm tip, this pen produces crisp, clear lines. The ink is quick-drying, helping to reduce smudging—especially helpful for fast writing or left‑handed users. The sleek, lightweight body feels comfortable during prolonged use.

Ideal for everyday writing, note-taking, sketching, or journalling, the TANK pen combines reliability, precision, and style in one tool.
