These numbers are exactly what I was looking for. I I need to put some very obvious address numbers in front of our house. We live in a hilly area and delivery people often aren’t sure whether to go downhill to our neighbors or uphill to our house. We do have numbers down but they are missed all the time. I will mount these LARGE numerals on a piece of even larger flagstone and have the whole thing mounted at the bottom of our driveway. 
They are very well made, heavy and super solid!
