Metacil 2H Metal Pencil Black
The secret is a long-lasting aluminum-graphite alloy tip, which doesn't require sharpening.
A writing tool that won't get your hands, pockets, or bags dirty, doesn't require delicate replacement leads, and lasts a long time (16km of writing, according to the manufacturer).
Write quietly, weightier than a standard pencil and has a cool, smooth feel, a matte finish, and an ergonomic octagonal shape.
It produces lines similar to a 2H pencil and can be erased.
Materials: aluminum alloy (aluminum)
This pencil cannot be used with a sharpener.
