Copplus Matte Brass Pen with Clip, Cap Can Be Screwed onto the Top of Barrel, Refillable with Parker G2 Style Ballpoint Ink Cartridges

For the money I am deeply impressed. There are no sharp burrs, and everything is finished reasonably well. The cap when screwed onto the front is not 100% concentric with the main body but it is such a slight difference it isn't really noticeable. The refill it came with is wonderful, almost as good as the g-2 by pilot which does in fact fit. Two things I want to note, the pocket clip can screw off. I was pleased by this. And the cap can be screwed onto the back of the pen, I know older versions do not have the threading.As stated the threads are fine and there are many. I don't mind this. The pen is also long, and fairly hefty. I also don't mind. Would but again.

It almost was the perfect pen. It takes Pilot G2 refills, the cap can be attached to the back while in use, the clip can come off, and it's solid (all the aspects I was looking for). But I don't like this pen sacrifices aesthetics for the important feautures/function I just listed. It is not seamless when the pen is closed nor when the cap is attached while in use. Therefore it doesn't have that minimalist look and feel I was looking for, which is just as important as the functions.

Works great, a hefty pen. It does fit g2 refills which is great.

Pen is ok. The cap takes too long to unscrew. Also the title recommends a refill that won't fit the pen. I bought refills that don't fit and I can't return.
