Later, I happened upon a thread where the the originator was seeking a small pen. I replied with the link above but then clicked on another's recommendation and could not resist the low price for this tiny Lanbitou Pocket Pen (I've seen it also described as "missle")and bought a few.
It's a fine writer, very smooth for an inexpensive pen. It doesn't hold much ink, of course. It feels very sturdy and is surprisingly long and comfortable to write with when posted. The body is very smooth and the section has etched ridges to guide your fingers, allowing you to grip properly without trouble.
I filled it with MB Oyster Gray and it worked fine for about a week before my Son-in-Law suggested it would be a wonderful pen for him. So my first Lanbitou has been happily gifted. I filled the next with a 50/50 mix of Noodler's black and water and it's performing very well. The fine nib allows me to write without bleed-through even on cheap copy paper.
It appears you can by a similar (or same) Jinhao-branded or "Yiren" pen in a variety of colors.
The Lanbitou Pocket Pen is a delightful little pen and I would not hesitate to recommend one--heck, at this price why not two?.
In the image below I've put it beside some other pens to help you form a good idea of the Lanbitou's diminutive size: A Pilot VP, Lanbitou posted, Lanbitou capped, Lanbitou un-capped, followed by a YongSheng 533, a Hero 266, an FPN-favorte Hero 616, and a TWSBI.
