Ohto (a lesser-known Japanese brand that specializes in roller ball pens and mechanical pencils) F-Spirit Fountain Pen is one of the most affordable non-disposable fountain pen in the market. It didn't take me long to make the buying decision as there are so many positive reviews on the Jetpens product page.
The pen as a whole is solid and substantial (not so much that it becomes a burden to hold) as it's made of metal barrel with some sort of resin (or lacquer?) over it. I am not too crazy about the cigar shaped design, since it not only screams 50+ year old corporate lawyer (another way of saying that it looks kind of expensive), it's also a little too big and heavy for my small hand.
The lid (along with the rest of the body) is also solidly constructed (with metal inner cap-like thing) and shuts a little too securely. The weight-per-length is consistent with the body so it doesn't throw the pen off-balance once posted. The model name, number (printed on the other side) and country of origin are printed by the edge and it didn't take long for me (the OCD scracther/peeler) to get it off. There is a ball at the end of the clip which is suppose to facilitate the attachment. However, the clip itself is so stiff that so the ball barely helps.
