It’s a great pen, but a bit scratchy. The
perfect point between 0.3 and 0.5 (seeing as
it’s right in the middle--duh). Surprisingly,
pens and pencils in 0.4 are a bit hard to find
these days, but this did the job just perfectly.
I tend to write with 0.5 mostly, but sometimes,
depending on the pen or lead, it comes out too
thick. The points and lead for 0.3 are too brittle
and scratchy, and the 0.4 is better for me. I
still prefer 0.5 overall, but it’s nice to have
0.4 as an alternative depending on the paper.
