I haven't posted much on here but because of the lack of information about the N1 pen from Moonman, I've decided to drop some thoughts on here.
This pen was purchased on Aliexpress for $20 (free returns option) and comes with a converter as per the listing description.
The pen is all metal and while it's not heavy, it's got some heft for a small pen. It feels slightly lighter than my Faber Castel Loom. While capped, the pen is slightly back-weighted but it's minor and doesn't bother me at all (a friend of mine does not like this however). The pen is comfortable to hold in the hand and while it's possible to write without the cap, I'll be using it posted. At the end of the body is a clear rubber ring that keeps the cap secure when posted and it works very well. That said, there's a hairline wiggle pivoting from the rubber ring to the body. It's very small but is noticeable while writing.
Onto the nib. This pen is a very smooth writer out of the box and did not have any issues or in need of adjusting. It's a firm nib, very little flex but is the smoothest fine nib I've used to date (sample size is small, 3 pens). If I could compare it, it would be like taking my Lamy Aion medium nib and making it a fine nib.
This pen came with a converter. It's small and as you might see in the pictures, just barely fits into the barrel. I was pleasantly surprised that after inking up the pen through the converter (not the nib) it wrote after a few seconds, no priming was necessary. The ink used is Noodlers Kiowa Pecan which is slightly on the dry side (compared to my sample vial which seems wetter.....). I plan to use Sailor green ink next time which is wetter.
I'd give this pen 4/5 with the only flaws being the balance and (very) slight cap wiggle.
