* All spring-steel frames are born with the desire to be in a relaxed comfortable round shape. When they achieve that position, they do not have any punch and are not very efficient anymore. Our OVAL PermaTense* design keeps them alert and extremely tense by providing a screen just small enough to hinder the frame from being in this relaxed and comfortable position. The OVAL PermaTense* frame and screen work in synergy and it becomes the strongest design when provoked to action.
