I've searched the forum review index and didn't find a review, so I decided to make one.
I ordered this pen from AliExpress for €1, with shipping and after it came and I tried it, I ordered another one for a friend.
The pen is too good for it's price, and the only issue I've had is that one of the pens came with a small crack that made it leak when shaken forcefully. The cracked pen has been in my backpack and my pocket, and it didn't leak even a tiny bit when carried around and it hasn't leaked while writing.
It's a demonstrator pen, that comes with a rubber ring, so that you could use it as an eyedropper.
Although you don't have to use it as an eye dropper, because you can use international standard cartridges or use the international standard converter, which it does come with
I've tried using it as an eyedropper too, and it worked without any issues. It doesn't leak from the barrel or anything like that.
The nib is pretty stiff, even for a steel non flex nib, but it writes pretty smooth, although not as smooth as a Pilot Metropolitan. I expected it to be a lot toothier for that price, but I was very surprised when I started writing with it.
The nib says F on it for fine, but it is a fair bit thicker than a Metro M nib.
The nib and feed are inside a plastic barrel (that plastic barrel is the thing that cracked a bit), and that plastic barrel is screwed into the plastic where you hold the pen while writing.
The pen posts wonderfully because it's pretty lightweight. I haven't had any problem with the cap falling off while posted, but I don't really shake my pen a lot while writing.
The only marking on the pen is the Jinhao etching in the metal part of the cap which can hardly be seen, and the Jinhao block letters on the handle of the ink converter that it comes with.
All in all a pretty nice pen, especially for the price, even tho one came with a crack it still wrote nicely and I haven't had a problem with it.
I'm still stunned, that it's cheaper to buy this pen that comes with a standard international converter, than to buy a standard international converter from AliExpress. Even if the pen is broken when you get it, you get a converter for €1, and that's very nice.
