Fisher Apollo Space Pen

Fisher space pens are used on all manned space flights: American and Russian. They write at any angle (perfect for that pen hanging from a calendar), you can even write upside down. They write under water, over grease and in extreme temperatures. The barrell color of the pen will vary with a chrome cap and black ink. This model is an affordable, inexpensive version of the original space pen and the bullet space pen, both of which The Space Store carries. Writes -50 degrees farenheit to +400 degrees farenheit. Lifetime guarantee.
