The Fisher Space Pen Black Grid Design Shuttle Ballpoint Pen is a gridded version of its Chrome counterpart. The all-chrome pen has ridge-pattern throughout the body. The beautifully crafted, metal body composition gives the pen a substantial weight but is well balanced. Equipped with clip and push button mechanism, the ballpoint pen uses revolutionary refill with pressurized ink which writes on unconventional surfaces such a greasy paper, in a freezing gold or melting hot temperatures.
