I was just looking at the website of the ujuku shop in Japan (where I recently ordered my Decimo) and saw an interesting pen:



The description reads:

"Fountain pen CUSTOM Extra Smooth FKK-3MR-B
Pen Point is cut aslant.
It can write smoothly also by those peculiar."

(I love these descriptions.)

From the close-up photos of the nibs, it looks like these are round oblique nibs. As someone who loves smoothness in fountain pens, the name "Custom Extra Smooth" got my attention. I am certainly peculiar, so that fits.

Has anyone ever tried one of these? Are they really extra-smooth?

Here's a link:
