I love the standard Uni Kuru Toga pencil, but the advance is definitely a step up.
I really like the retractable lead sleeve and that it also slide into the pencil as the lead wears down while you write.
It might not look like a "high end" pencil, but neither does it look cheap.
It's got a reasonable ergonomic grip, but to me, doesn't feel quite as good as the standard Uni Kuru Toga - but there isn't that much difference.
I like it a lot.
