Model #'s and info on inside of Glasses arm - RB 3548-N 001/8O 51.21 145 3N Lightly used sunglasses in good condition. Some blemishes on frame barely noticeable and some small scratches on lenses. Final picture was an attempt to capture the micro scratches, however it is extremely hard to see. Awesome Glasses however I have grabbed a new style and ready to part ways with these. Comment with any questions!
