This European-style glass mirror has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the mirror surface is generally narrow and easy to carry; the mirror is mostly used for shaving and shaving, and the mirror surface is only enough to shadow the partial beard.Then, with the passage of time, the silver mirror used by most of us came into being.
