I really like this kit. It seems like a solid little pen. The nib end of the ink cartridge seems to come out a little farther than I like. But thats just my personal taste. I can't seem to get them much past the front door when I finish them. They get "claimed" for others.
The mini ink cartridge (Pocket Pen cartridge) fits in the screwing tube section kind or loose at times. I've been crimping the metal section so the cartridge doesnt fall out.
The click mechanism works well. Its a fun little pen!
Here are my "fixed" photos - and another one.
