Solid pen

I carry it every day. Perfect pocket pen.

Awesome pen.

I love just about everything about this. It feels satisfyingly weighty but not uncomfortably so. It’s very precisely machined, so everything feels smooth. It takes standard Parker-style refills, so you have a ton of options to suit your writing preference. The only thing I don’t love is that the bolt action motion can cause you to untwist the pen a bit, but it’s really not a big deal. Everything else is perfect!

Very classy and well built pen!

Writes very well! Extremely heavy. The bolt action is nice and satisfying. Wish that it didn’t loosen as easily as it does, but this does not hamper your writing experience. 10/10 would buy again. It’s a real treat watching people react when they see it for the first time.

Nice Pen!

I like the pen very much — it is brass and I have not seen that often in this type of ‘heavy duty EDC’ type pen. Copper, yes, but brass, no.

I do find that it starts to ‘unscrew’ with constant use and I have to tighten it up again. Both the barrel and the slotted bolt-handle do this. I am considering using some light-duty loctite glue to hold it together so this is not as annoying.

Amazing....please read

I spent a considerable amount of time researching for an EDC (every day carry) pen....I wanted a high quality pen, a pen that writes very well, that is very strong and most of all a pen that looks amazing.....most EDC pens are very durable, BUT what makes Inventery different than the rest is the quality of the pen and for me the number one reason is that the pen is absolutely beautiful....I would not hesitate taking the pen with me if I was going out to a nice dinner...It is obvious that a lot of thought and effort went into the design of the pen.
