These are very lightweight sunglasses, weighing only 21g. I purchased them at Megane no Sanjo (Paris Miki). Sunglasses are a necessity for the coming season. Below are the sizes of each part. Please use them as a reference: * Lens width (horizontal): Approximately 5.5cm * Lens width (vertical): Approximately 4.3cm * Bridge width (nose width): Approximately 1.2cm * Frame width: Approximately 12.5cm * Temple length: Approximately 13.7cm Additional information: I always thought they were Ray-Ban, but it turns out they are a Miki original brand. They weren't cheap. I had them cleaned at Miki.
