Again, a beautiful piece of gem from BigIDesign

This is one of many other pens that I bought from BigIDesign and again, this is a beautiful and solid pen that I will use for many years.

Originally, my main concern was about the shipping but in the total of 5 times that I placed an order, the shipping was fast and clean.

For the pen itself, stainless metal, quality refill, manufactured with care, I don't have anything that gives me the chance to drop half a star.


LOVE this pen. Big fan of the Hi-Tec refills and the weight of this thing is crazy. I have other steel pens but this thing is a club. It feels great in your hand balance wise. I think they heard the complaints about the back plug coming unscrewed because mine came TIGHT, like it completely destroyed the first penny I used to unscrew it. Other than that it's been fantastic. It lives on my desk and I use it to mark schematics. My only other note is that, yes, if you try to post the cap while you're writing it's terrible. The cap is a huge hunk of steel and it makes the pen backheavy to the point of it being uncomfortable to use. That's fine with me because I never post the cap anyways. Otherwise, it's been amazing.

Awesome product but ink doesn’t work

Received my PHX pen recently and I’ve been loving it so far! The weight is pretty surprising at the beginning but you get used to it. Seriously you could knock someone out with this.
The finish quality and writing experience are also top notch.
However after writing a few lines, it stopped working. First it was really scratchy and then no ink flow at all. Pretty disappointing...
I’d still recommend it if you enjoy heavy pens, it remains a great writing tool.

Hi Theo, sounds like you have got a faulty refill, please feel free to shoot us a quick email at, we will be happy to help you out asap.

awesome products!!

received my PHX today and it is fabulous! weight is nice and is comfortable to write. highly recommended!

Amazing and simple.

Simple, light weight and reliable. A perfect everyday carry pen that won't let you down. I even love the way the ink cartridge that comes stock writes. For the price tag, this pen is unbearable.
