Ordinarily, the lead of the pencil is filled in the full of its length.
It's hard to use the lead from end to end even using the extension holder.
Forget about it.
On "easy pencil", 60mm shorter lead is embedded in the pencil.
That means the easy to use the lead to the end.
Expending the all lead is the time to treat new one, without hesitation.
length of lead: 116mm
material: Japanese cypress / graphite urethane coating
