Space pens are sweet, you can write upside down and even underwater! What makes this particular pen from Fisher even cooler? Is that it’s made out of a H&H .375 caliber magnum shell casing!
It does all the cool things any space pen can do, but it looks so much cooler. Just don’t take it along with you when you plan on traveling by plane. You can get your own bullet space pen from vat19.com for just $25.
