Pentel Orenz 0.5mm 鉛芯筆
Pentel Orenz 0.5mm Mechanical Pencil is exactly the mechanical pencil you were asking for. Finally, a pencil which leads do not break. Equipped with an orlens system in which the tip pipe slides as the core decreases. Because it can write as long as the tip pipe, the amount of writing per knock is three times that of a typical mechanical pencil.
