The perfect mix of tradition and technology, the Espro Press combines the standard glass french press with a double micro-filter for a cleaner cup without the grit and silt at the bottom of your cup! Cleanup is a breeze with this full contained filter. The Schott Duran Glass is designed to be 40% thicker than a traditional press and locks into the metal cradle using the Espro Safety Lock system - preventing the glass from sliding out during pouring.
