For me, there's no such thing as too fine a line. This is another super-fine pen
to love. A little scratchy, a little dry, and the tip feels a little
delicate--but no more than to be expected. The Kuretake Tegami Letter Pen
super-fine refill edges this one out because it's smoother and less dry with
easier line variation, even using rapid strokes (I don't have the Tegami nearby
to compare, so I'm going from memory on this). But I like this one enough to
pick up the black and the grey too. I'm enjoying it for intricate doodles and
warmups, detailed crosshatching and small lettering. The sepia has maybe a
little more grey in it than some variations on the colour.
I didn't purchase the holder (I think the way the refill pokes out the back is
unattractive, except maybe for the "starry night with glitter" black holder,
since it matches the glittery black ink reservoir), but I have no trouble using
the refill alone as a pen. Larger hands may want the holder for convenience, and
it does come in nifty colours.
This pen writes very nicely; I didn't buy the body so I just write with the
refill and it's fine. The ink, however, runs out rather quickly and if i store
the pen point down, it bleeds a lot (therefore wasting ink) so I just store it
upside down. The colour is very nice and I love writing letters or writing small
with this pen! It's a little pricey now but it's a good buy!
