Platinum Carbon Desk Fountain Pen

I got to try a new fountain pen (thanks to JetPens), the Platinum Carbon Desk Fountain Pen.  I was very impressed by this pen the nib is very thin, the ink flows wonderfully and the the price is very affordable.
The feel is not far from my Namiki Falcon (the nib is extra fine) and the ink that comes in the cartridges is permanent.
