100% authentic. These glasses are broken. Although everything is still attached/screwed together it is dented due to my dog trying to eat them. If you are a “glasses/frame” expert or tech maybe you can fix them or replace certain parts. There is minor scratches and bite marks on one side of the lenses/glasses. These are prescription so you’d need to replace the lenses either way for your prescription. If you think these frames are an easy fix or you can send to a professional to get it fixed I recommend purchasing. They were worn less than a handful of times. I never liked the style because they dont fit my face shape so i never bothered getting them fixed
