Spacetec A1 ballpoint pen chrome

The SPACETEC by Diplomat pressurized refill writes with the tip upwards, underwater, in fiery heat (up to 200 ° Celsius), freezing cold (up to -50 ° Celsius Grad), and in particular in the empty without gravity. Your pen will be able to write nearly 5 killometers, before requiring a refill, three times longer than most ballpoint pens.
