Using the Gentry Rectangular Mirror is easy. You can hang it either horizontally or vertically thanks to the two metal cleats on it. Before hanging, make sure to measure your space and check the product dimensions to ensure a proper fit. Since it's made of natural marble and brass, there might be some slight color and size differences, which is normal. This mirror is for indoor use only. To keep it in good condition, simply wipe it with a soft, dry cloth or a static duster. Never use harsh chemicals or abrasive cleaners as they can harm the finish of the mirror.
