What is the function of toilet cosmetic mirror?

There is usually a big mirror in the bathroom, but the big mirror can only take the whole image. You must also have a cosmetic mirror to take photos of facial details. Can be stretched, very convenient. Through the triple magnification function, women can clearly photograph every detail of their faces when making up and caring for their skin. You can cooperate with a big mirror to get the effect of a new hairstyle. When a man shaves, there is no need to put his face in front of the big mirror so hard. The triple magnification function of the mirror can make the beard see clearly and pick it clean.

I saw it in the product brochure of ellin bathroom last time, and it was very detailed.
