There is one major flaw in this pencil: when it's being used, the 0.9 lead often
slips back into it. This is not just a problem for when I used it, but also
when others tried to use the pencil. And this is very frustrating, especially
considering that this pencil even says 0.9 mm (lead) on it. Maybe I just
happened to get a defective item.
Other than that, it is a pretty nice pencil. It feels good in the hand, it has
a rounded-triangular prism-like shape that prevents it from rolling off of
tables too easily.
