The company's main office is the Penris Building, located on Swiss Street in Pillbox Hill, Downtown Los Santos, next to the International Affairs Agency Building. The business also has offices on Marathon Avenue in Rockford Hills.
The name is a pun of the word "penis". Nothing else is known about the company and it plays no part in the storyline whatsoever.
The company is a parody of Orbis, therefore most likely being an opthamologist association, as its eye-shaped logo suggests.
