The Trodat Mobile Printy is designed for easy, ONE HAND operation. A simple "pinch" of the mechanism opens the unit and exposes the printing die. There is no need to remove a cover. The unique "pyramid shape" design (when opened) provides stability to the baseplate and evenly distributes the pressure, ensuring a clean, even impression. The patented ink pad design makes re-inking or replacing the pad clean and easy. The design is modern and attractive. Image size: 9/16" x 1-1/2"
