I got these sunglasses as part of a collection of 80s - 90s sunglasses that was passed on to me by my late uncle. I don't know the brand, the only markings I could find are "China" on one of the arms. They seem to be well made, not flimsy. The lenses might be glass, as they are kind of heavy. There are a few very minor scratches on the lenses, but still usable in my opinion. The hinges are very slightly loose, may need to be tightened.

Feel free to message me with any additional questions.
