This flat-frame metal&acetate combination sunglasses is made of a 2-layer acetate sheet with a black surface and a tortoiseshell color underneath. The top of the frame is carved one level lower and embedded with metal steel piece that crosses the eyebrows to form a three-step step. Then, the dark brown sun lenses are assembled to make the whole frame look very strong and muscular.

Honeycomb hole stainless steel temples with a rectangular small area inside that can be printed with your logo. The stainless steel tail needle is inserted into the acetate tips.

Single brown sun lenses with high transmittance, inner-coated with AR anti-reflective blue film, 100% UV blocking, more effectively protecting the user's eyes.
