Pentel Sharp Kerry
The Pentel Sharp Kerry is a mechanical pencil that also features a cap and the ability to post, much like most fountain pens and some rollerball and ballpoint pens. When posted, the tip of the cap of the Sharp Kerry can be removed to reveal an eraser beneath.
When unposted, the tip in the same place can be removed for access to the interior lead tube of the pencil.
The Sharp Kerry is available in a wide range of colors, in lead sizes 0.5 and 0.7.
