What is this? Valco sunglasses. The lenses have UV400 protection and are polycarbonate. The temples are bamboo and the frame is plastic. A case and a cleaning cloth come with them.
Two models. Black turns the world purple, just like in D12's Purple Hills video. Nothing beats Purple Hills, at least according to rap professionals. The brown Nostalgia model turns everything into an 80s Indian summer.
What they are not for. The glasses are not suitable for welding. Looking straight at the sun is not recommended with them either, and especially not without them. Their main function is to look cool and earn respect from others.
Ordering. Delivery is free. You get 14 days to try them at home, and the warranty is 2 years.
