Each pencil has click mechanism; simply click the button at the top of the Zebra Color Flight to produce as much graphite lead as you need. No sharpening, no wastage! These Color Flight features a nifty twist mechanism for the eraser situated at the top end of the body - twist the eraser to use and twist anti-clockwise to push it in.

The pencil lead is 0.5mm and produces sharp, thin lines.
