Most of our lives hover around electronics, but there are those of us who still use archaic writing utensils such as pens and pencils. The most frustrating thing about these writing implements is that they break or just stop functioning on occasion. If you do enjoy scrawling out words or doodles quite often, you know how attached you can become to one pen or pencil. If it’s not particularly well-built, it will eventually break and/or run out of graphite or ink, which can be quite devastating.

If you want to prevent that sad day from ever happening again, then why not get the World’s Most Reliable Pen? This was created by Fisher Space Pen for NASA astronauts, because they don’t exactly write in the most stable of environments. Inside of this titanium nitride shell is a high-viscosity thixotropic black ink that will last a very, very long time. It’s sealed in with nitrogen gas which means no leaks, and that assists the tungsten carbide ball to write cleanly and clearly in a temperature range of -30-250 degrees Fahrenheit. This $150 pen has a clip, and hopefully comes with a lifetime guarantee, you know…just in case it’s not actually that reliable.
