Have a great idea in an unconventional situation? Use this Tradesman Cap-O-Matic Space pen to write upside down, under water, over grease, in extreme temps—plus, it's easy to see if you drop it.

  • Features

    • Replaceable pressurized ink cartridge continuously feeds ink to the tungsten carbide ball, allowing pen to write at any angle—even upside down
    • Thixotropic ink writes smoothly and dependably on most surfaces, even under water, on photographs, in freezing cold, extreme heat and in space!
    • Revolving ball liquefies the ink so that it writes more smoothly, more dependably and longer than most pens
    • Hi-Viz Yellow finish can be spotted from 100 ft. away if you lose it on the job site or outdoors
    • Materials are recyclable
    • Nontoxic black ink; refills available (not included)
