Great Pen

The Bastion Bolt Action Pen is really well made, especially for the price. The machine work is very precise. It screws together really well and stays together even when using it all day. Well worth buying.
- Alastair Johnston

Best quality pen I've ever used!

For starters, this thing is HEAVY. And I mean that in the best way possible. The quality in person is so much better than what you can really tell in the photos. I am a machinist by trade and am VERY impressed with the quality and perfection of the machining.

Beautiful and Awesome

Nice weighty pen with quality fit, finish and feel! Great for us with larger hands. Would have preferred Schneider or Space Pen ink cartridge to the generic cartridge it came with. But that said, The Quality is Awesome!
- Montana Cowboy

Very Elegant

I use this thing to write everything from parts lists, to addresses, and even doodles on cardboard boxes. The coating is strong and durable, it’s held up after being shoved in a pocket with other tools for 2 weeks now! 10/10 would recommend!
