I’m not a sunglasses person by any means. I only ever bought the cheap $5 sunglasses for years cause I didn’t care to wear them anyway and I never liked how they looked on me. THESE HOWEVER. Jaw dropped. I love them. I wear them everywhere. I care for them and clean them like they are my child. They are the best investment into sunglasses I have ever made.
