Keeping up with the whole writing theme, we have the Sentryman Explorer Pen. I … am not such a big fan of this item, but yeah, there is probably a niche for it out there.

My main problem is … it’s a pen. But it sort of … got turned into a luxury items. Sure, it’s durable — and hey, it can withstand any number of temperatures, cold or hot, I guess. So, that’s great! If you get trapped in a volcano or on a glacier, your pen will be fine.

But wait, that’s not all! It has a flint right in its barrel. Okay, it’s artificial flint, but that will still let you start a fire — if you have some magnesium handy, of course.

And hey! The cap glows in the dark!

To be fair, the pen was first designed for people exploring in the South Pole. So even though you are not an explorer, you can write like you.
