Editor's Notes Frenzy draws influences from 1960s art fashion. This butterfly-shaped frame with avant-garde nods can accentuate a daring aesthetic or blend in with more casual looks. Each pair is handmade in limited numbers to maintain precision and quality that will look great and last for years. We plant a tree for each pair of glasses sold on our website in partnership with Eden Reforestation Projects.
