There are few non-mainstream sunglasses. Unless it's big enough to cover your face? So who will buy it? Simply put, the non-mainstream is unacceptable to the public. This is an outrageous exaggeration. When describing the appearance, it has been equated with killing Matt. Killing Matt is indeed a representative of the non-mainstream and the originator family. Many people confuse it with fashion and trend, but it is far from it. Please adopt or ask.
