Ray-Ban Frame Quality
Ray-Ban frames are made from specially composed metal alloys (or the finest) plastic and are formed in a series of exacting operations. Each frame style has been carefully designed to fit properly and comfortably, even for extended wearing periods.
In the Ray-Ban Classic Metal models, a layer of almost pure gold (24 karat) has been permanently bonded to core metal specially alloyed for both strength and malleability.
In the Black Chrome models, the layer is black chrome -- not an enamel that could chip or wear off.
