Part of the Mad World Collection, the Sabre "Madness" is part of the eyewear groups Fall 2008 line. The frames are a mix of shiny and matt handmade acetate with CR39 lenses. For hinges, the "Madness" incorporates new technology which allows for easy switching of the arms. Two of the four color options - a black with white and teal arms and a black with stripe arms - come with two arm choices.
