What in the world are these funky looking things? Well, my friend, these are Mushroom Markers. Although they look a  little goofy, these are a perfect, eye-pleasing solution to protecting your curb. Do you live on a corner lot and people cut through your grass too often for your liking? Put down some Mushroom Markers. Neighbor parking cars on the edge of your yard? Mushroom Markers. Just want a unique border for your landscape? Mushroom Markers.
