This Faber-Castell Emotion fountain pen is actually one of the first 'real' fountain pens I bought, so I've had it for quite a few years now!
As with the pencil I reviewed earlier, this pen is rather heavy , because of the metal parts, I suppose. This makes it feel very solid. The weight is perfectly balanced, so there is no need to post the cap (which isn't possible anyway, the cap doesn't fit the back of the pen!) Obviously the chrome parts of the pen attract fingerprints, but if you are like me, and you always have a polishing cloth at hand, or if you just don't mind, this isn't a big deal either!
I chose the black wood barrel, even though this didn't match my Emotion pencil, but I love black pens, so I had no choice!
Now for the nib, first of all, I chose a fine nib, which is strange because I normally always stick to Medium nibs. But as soon as I wrote with it, I remembered why I chose this one: it writes perfect, not too thick, not too thin, just perfect! It doesn't skip, the inkflow is consistent. And the nib itself actually looks quite good as well. The nib gives a slight feedback when writing, it's not scratchy at all, but it doesn't feel slippery, which is a good thing for me, it writes very controlled! I also found that it has a little flex in it, not much, but it is possible to make some line-width variation.
I consider this to be one of the best fountain pens I own, and I like the fact that it is something different from my other pens because of the F nib.
Nowadays you can get them for around 100 Euros/ 135-150 USDollars. But mine is actually the cheapest model, there are some models with engraved barrels and such, that are a little bit more expensive.
