> what the hell are these brands?

This is what 1-man-brands are. I myself used to run a sunglasses brand in my student years :)

Most are just dropshippers, or people working out of home.

Recipe was simple: order cheapest 1 dollar sunglasses on Alibaba, have them put into fancy packaging and silkscreened with something Italian sounding. Then you make up a generic website with stock photos for your "brand"

I was surprised with the amount of people keen to buy $100 to $200 sunglasses with nothing more than an Italian sounding brand name.
