Mitsubishi 1.0 mm Uni PowerTank Retractable Ballpoint Pen, Blue (MI-SN220-BE)
Pressurised refill provides writing ability in extreme conditions. The Uni PowerTank will write on wet paper; upside-down; in temperatures down to -20 degree C, and even in zero-gravity. Just like a Space Pen – except the whole PowerTank pen is less than half the price of a single ‘space pen’ refill. 0 mm Ball writes a 0.4 mm line. Retractable with chunky rubber grip. Ideal for outdoor and professional use.
