Zebra DelGuard 0.3mm Mechanical Pencil
With the DelGuard mechanical pencil, you will never have to worry about breaking the lead! It has two unique mechanisms: when too much pressure is applied vertically, the lead retracts automatically, and the same happens when to much pressure is applied laterally while you write. With this, it is impossible to break the lead. The 0.3mm thickness allows you to create fine lines and have a delicate and discrete writing.
