The Lamy Studio ballpoint in Brushed Stainless Steel has wonderful balance and weight, making this a very comfortable pen to write with! The silver matte lacquer body and cap accented by the propeller-shaped bright chrome clip, make this an extremely appealing pen design.  The Lamy Studio ballpoint has a twist action mechanism to extend and retract the refill, and it uses the Lamy M16 ballpoint refill.
