About ten years ago I bought these folding Persol sunglasses and then a few years ago I dropped them and they cracked in half. They've been sitting in my drawer since then. I tried everything I could to get them repaired but no one would even attempt this tricky repair (since they fold) Finally, SpecMedic was able to help. It was a great consumer experience. They have a very simple website, the spec medic called me to discuss my repair which only took a day or two, and they shipped them back to me quickly, all for $30.
