OASO K018 Sealed Retractable Fountain Pen Set 0.5mm with 2pcs Blue Ink Cartridges Smooth Writing for School Students (Black)

I think it's important to spend some time with a product before rushing off to write a review, particularly with clicky fountain pens like this. I've bought cheaper clicky pens before, and while I found them fairly impressive on first impression, that impression quickly changed when the nib dried out in a very short amount of time and the pen became unusable. I am happy to report that is NOT the case with this pen.I've owned this pen for about a month, and it hasn't dried out on me, and I've even gone days without using it, something some of my non-clicky fountain pens sometimes struggles with. So I think I can say with some confidence that the seal protecting the nib actually does a good job.The nib is smooth, and writes a solid, I'd say, extra-fine line. More nib options would be great, of course, but I don't think you can complain too much at this price point.I think this pen is about as good as one can reasonably expect a clicky fountain pen to be at this price point, and is probably about as cheap as you should go if you just want a clicky fountain pen. Sure, there are cheaper options out there, you can pick up a clicky pen for no more than $2 or so, but you're almost certainly going to run into issues of those pens drying out, probably within a few hours of inking them up. This is a very solid pen.

The quality of this pen, the light weight, the retractable nib, ink pen is such a massive bargain! I have been ignoring other far more expensive fountain pens in favor of this one. Lovely ink flow, great grip.

A bit scratchy at times but it’s alright for the price.

It writes unexpectedly well for such an inexpensive capless fountain pen. Easy to use and ink cartridge installation was quick and easy. Came with a black and blue cartridge.

Nib does not dry out unlike most fountain pens. Only downside is the ink cartridges are not the standard ones.
