三菱鉛筆 Uni Jetstream Edge 0.28mm Oil-Based Ballpoint Pen, Navy Body (Sxn100328.9)

Uses a dreadfully small D1 refill which runs out quickly and is expensive to replace, the pen's upper is made of plastic, totally not worth it for the price.

The pen is well built and writes smooth even with a tiny tip. So it does what it promises. However the oil based ink is too weak for my taste. Wouldn't be my daily pen.

When it works, it's really interesting having a tiny ball... but the ink doesn't flow properly for long. It lasted 2 weeks and then is only working on and off. :( Concept is interesting, though

Just what I need sharp lines and smooth

This pen has become my new favourite for everyday notes. The tip is incredibly precise without feeling scratchy, and the ink flows really smoothly. The navy body looks smart and feels great to hold. If you like clean, fine lines and a pen that just works every time you pick it up, this is a brilliant choice. The only issue I'd say would be the way it sits in my hand specifically leaves a mark on my finger after intensive usage.

I already have good pens for daily writing like the Zebra Sarasa and the Uni Jetstream 4&1 Metal body, and I don't write in 0.28 very usually. This pen is like a cool trinket for use in very niche conditions, and I mainly got it for the body and the novelty. I like the body, I used it with the 0.7 jetstream multipen refill and its wonderful, but I still prefer Zebra sarasa. 0.28mm is also very thin and isn't very smooth, as expected. Only get this pen if you have an already large collection of pens and pencils. I do, and I like this pen. Do mind that the ink was skipping so i got the whole pen refunded.
