Feng Shui Wood Bagua Mirror Enhancer or Container
These mirrors are used to enhance or to deflect energy.
Place a convex mirror outside an entry door to keep out negative energy.- OR - place it on an outside corner of a home to deflect "Cutting Chi" (energy that is slicing through and into your home). This can occur when a dwelling is above or situated oddly with a corner of their home "cutting" into yours.
Place a concave mirror outside or inside at the entrance to increase energy. This is useful when the entryway is obstructed somehow - perhaps the door is turned and is not visible from the front of the home, so energy has trouble entering easily.
Both convex or concave mirrors are 4" in diameter.
