Precautions in use

Pencils・colored pencils ：Why is the lead broken

Same as pottery, the lead of a normal pencil is made strong and does not break easily. However, the lead might be broken by a sharpener with deteriorated blade, strong press to the hole of sharpener, being pushed straightly to different directions.
