Normally, the lead of the pencil is filled in the full of its length.
At any cost, it’s impossible to use the lead from end to end.
On “easy pencil”, 60mm shorter lead is embedded in the pencil.
That creates the possibility to use the lead to the end.
New pencil is treated as expended the all lead, without hesitation.
“easy pencil” is able to be manufactured by only using shorter lead, without changes of current manufacture of pencil.
It is unnecessary to invest new technology or skills for manufacture of “easy pencil”.
length of lead: 116mm
material: Japanese cypress / graphite urethane coating
