So, that this design is to set the pencil's head to become rotating telescopic. The ring on the pencil's body can be rotate to adjust, changing the thickness size of the pencil's head.
With applying ISO specifications, the thickness of pencil's head can be adjusted to 0.12, 0.35, 0.5 and 0.7mm.

This ring is design at the place between the index finger and thumb when writing, so that it's easy to adjust.
