New Nakaya fountain pen

Day before yesterday I got a large box in the mail.
Most of the contents was air, but the rest was really something I've been waiting for: A Nakaya Celluloid fountain pen, in Goldfish colouring. It was very well packaged and even came with documentation showing which craftmen had worked on it.

I ordered mine with a "music" nib, which means it's pretty wide with a large difference in how wide strokes in different directions are.
It's very beautiful and is extremely nice to write with. So I guess it works well to tell about your writing angle and so on.
First ink I put into it is Platinum black.
