I was surprised by the volume of the mechanical pencil by opening the package. I tried to remove the curiosity. I found a gum almost 5 cm, easy to replace. However, mines are recharged from the bottom, definitely a blow to take. Pros: Solid, retractable mine, the grip at the grip, the form of refined grip on both sides for a closer grip, the mine seven slides good on paper, pretty dark, and we can erase without leaving any traces, pretty metal blue. Cons: charging at the bottom, a compact mechanical pencil.
