So, how do we determine with any amount of certainty what type of mirror we are looking at?
Just conduct this simple test: Place the tip of your fingernail against the reflective surface and if there is a GAP between your fingernail and the image of the nail, then it is GENUINE mirror. However, if your fingernail DIRECTLY TOUCHES the image of your nail, then BEWARE! IT IS A 2-WAY MIRROR!

DIRECTLY TOUCHES the image of your nail, then BEWARE! IT IS A 2-WAY MIRROR!
"No Space, Leave the Place" So remember, every time you see a mirror, do the "fingernail test." It doesn't cost you anything.
REMEMBER. No Space, Leave the Place !!!
