The Retro 51 Tornado Pencil in Albert, is a 1.15 mm pencil that operates with a simple twist of the top and has a huge eraser on top for those of us who make an occasional mistake. The Albert Pencil features a matte black lacquer finish over stainless steel, with Einstein's equations written in white, accented with antiqued trim.

 They are just as easy to use as their rollerball cousin, and come with a generous supply of extra lead and erasers.
