The Aurora Thesi is an ultra-flat ballpoint with an oblique end and a differentiated non-slip satin finish. This modern, and functional design has a place in New York's Museum of Modern Art. The Thesi features a clever push-slide mechanism and a one-touch retractor button to pull the writing point. The Thesi refill allows for more than 10,000 meters of continuous script, making it a pen you can count on for all your writing needs.
