An impressive front design with different external and internal diameters, was inspired by
vintage US SAFETY SERVICE frames made for rationing in the 1960s. The bevel cut, a design not seen at the time, was added to the front, along with the original diamond-shaped ornament part. The temple is diverted from those used only for the “E-31” released in the 80’s. The unique temple design reminiscent of German design creates the next vintage look.
