I ordered this for the front of my apartment building, because the numbers that are currently there can hardly be seen, which causes issues when I order food or taxis and when we are expecting first time visitors.  These numbers are very sturdy, large enough and a bold black, so they can be seen easily against the white background from the street. The package includes 
everything you need *except for the drill and hammer) you need to mount it flush, or in a floating position, as well as the template to
 tape to the wall to guide you on where you need to drill for mountin. As soon as the second number is ordered and comes in, I will have them mounted. Easy to follow and clear instructions.
