I'm always a little suspicious of brands that are only available from Revain. This is one of them. The glasses arrived quickly. The product was nicely packaged. The frames are exactly as shown in the photos. The box only says "Made in China" and no other markings. The quality is very cheap. Most importantly, they do not block blue light. Not at all. It's exhausting figuring out which brands to trust these days. This brand is definitely not legal; Another scam product from China.
