Fisher Space Pen Bullet

Imagine being able to write a date on your calendar without your pen skipping. This is just one of the many challenges Fisher faced when it attempted to create a pen that could work in outer-space. The Space Pen utilizes revolutionary technology to make sure it performs in a variety of situations. Upside down, its side, through water, or in extreme temperatures, the Fisher Space Pen contains a sealed pressurized refill (SPR) that will perform. Even if you aren't a space explorer, the Fisher Space Pen can guarantee you can record every event of your next adventure without a second thought. 

The Space Pen was developed as a result of Fisher's experiments with new ink formulations and method of pressurizing a pen. When astronauts started to explore the reaches of outer-space, Fisher realized that no existing pen could perform in the boiling hot, freezing cold, gravity less void. Fisher designed and patented a pump action AG7 pen that would pressurize a special ink for about 30 seconds of write out so pen could write at any angle or zero gravity.  A patent was applied for then granted and the AG7 pens were sent to NASA, tested and approved for use.
