Berlin is a true panto shape with it's key hole nose and distinct shape. Berlin is larger than Anaheim and consequently fits a bigger head as well. Also the frame is slimmer giving it a different look from the more chunky Anaheim.
The frame is made of high quality acetate with profiled "gold" rivets and hinges.
Crystal rocks. Also with sunglass lenses. There is still a warmth to our crystal which is not always the case with cheaper versions of crystal acetate. And again - the gold inlay in the temples is a refined detail.
