The Astronaut 'Anti-Gravity' Dark Matter Black Titanium ballpoint pen relies on a simple click mechanism that allows you to press down on the top to extend the refill and an ergonomic side button that then retracts the refill.
While the design is sleek, the true beauty of the AG7 is the hermetically sealed Fisher pressurized ink cartridge (SPR). The ink refill is designed to exist in a chamber that is not affected by air or moisture. The result is a magical pen that can write under any weather conditions, with or without gravity, and in any direction without drying out or leaking.
