I absolutely LOVE the way that it feels and writes, but I've noticed that with
both of my 0.3 graph 600 pencils, the lead will sometimes not extend when the
end is pushed down. I've tried various things to fix this, but I can't seem to
find a definite way to cure this problem. While this is a big problem, every
time it has happened, I have been able to, at some point, fix them, so I still
give this 4 stars.
(is anyone knows how to fix this, please let me know, thanks)
