The purpose of this Ivy Collection Black Metal Wall Mirror, apart from home decoration, is to bounce back outdoor light to a small room to create the illusion of space. Specifically, this round wall mirror complements narrow entryways, small contemporary-themed bedrooms, hallways, and transitional spaces between rooms. Despite the seemingly heavy frame, light and durable materials were used to create it. The diameter is 35", and it hangs via a metal backing. Suitable for indoor use only.
