pocket is a beautiful font style that allows you to quickly give a modern, bold, organized effect to any text string.
To install the pocket font simply unzip the archive and put the font file (.ttf, .otf) into /Library/Fonts . The pocket font integrates quickly into your system and you can easily access the custom glyphs though any text editing application.
Mac OS X comes with pre installed font styles and pocket will simply be added to your pre existent library. The process is managed through the Font Book application, where you can easily browse and preview your currently installed fonts.

NOTE: The pocket font is free for personal use only.
