- In extreme freezing and boiling temperatures of -50° to +400° F.
- Upside down and at any angle
- Twice as long as other roller ball pens
- On shiny surfaces such as photographs
One thing I really like is that the pen is only about 3 inches long with its cap on so it fits easily in my front pocket. With my latest attempts to stay organized Hipster PDA-style, I always need to carry a pen with me. The Space Pen is a good fit for this.
