Purchased two pairs of these sunglasses. The ones with the silver, mirrored lenses came broken. The nose piece was broken off in the package. The metal frames feel sturdy, but the choice for a paper clip type metal with a nose piece attached makes them not very durable. I tried to crazy glue it back on, but it’s not the king of metal that bonds well. The black lense glasses came fine, but I will have to be very careful with the nose piece. Not happy the silver ones are broken.
