Reflective Driveway Markers, Driveway Reflectors, Snow Plow Markers 2-way reflector 43 Inch White Fiberglass Rod,Snow Markers for Driveway and Lawn/Yard/Property Line Markers (Pack of 8)

If you aren't going to invest in metal stakes, these will do just fine. I don't bother with metal stakes because if my plow guy is going to hit them (and they always do), they are going to get mangled either way. These will get the job done. The only thing that may be a problem is that the stakes are white so they will sort of get lost in the snow and be hard to see except for the reflective part at the top.
