Power Tank Ballpoint Pens
Power Tank SN-220 ballpoint pens by Uni-ball are the perfect pen for extreme or challenging conditions. They feature a pressurised barrel that will deliver the ink when writing at any angle and work on wet paper, in freezing conditions (up to -20°C) and even in zero gravity.
The Power Tank is the pen for field trips, or if you need to take notes in difficult conditions or you are an astronaut! Used extensively for geocaching as writing will remain in any conditions and always be read.
The pen has a rubberised grip, retractable nib and the 1.0mm nib writes a 0.4mm line. Available in black and blue.
