No ink I have thus far used on this paper has feathered or bled through. It is
excellent in that regard, and has a nice weight to it. However, it is extremely
glossy, almost slick, in a way that I definitely did not anticipate. Rohrer and
Klingner's old gold green ink on this paper almost feels like it doesn't take
(It does. The low viscosity of the ink plus the smoothness of the paper just
makes it feel like it won't.). Note that these observations are from a dip pen,
not a fountain pen though. It's vastly better than regular printer paper. Just a
warning that the surface is very slick.
This is probably one of the few blank spiral bound notebooks of good quality
around. My quips with it are mainly stylistic personal preference (for example,
I wish the outer corners were not rounded). The paper is indeed incredibly
smooth to write on. It is not suitable for fountain pens though. Quite a lot of
feathering and bleeding through.
I adore this pen. It is loud when it writes, but I don't mind at all. The feel
is incredibly smooth and the ink is satisfyingly dark. Oh yes, for non-drawing
purposes (i.e. normal writing), the .3mm/005 is right.
