The Pilot Opt mechanical pencils has unique body patterns which mimic herringbone fabric, pink stone, silvery stardust, and other interesting materials. It also has a clip with spring which lets you clip the pencil on your notebook, shirt or pocket with ease.
The 'Shaker' mechanism allows you to extend the lead by shaking the mechanical pencil up and down. The conventional method of clicking down on the cap works too. Used together with Pilot’s super smooth and super strong pencil lead, your writing will be clean, dark and you won’t be slowed down by lead breakage.
