If only the Druids had known how easy it is to install the RTS Home Accents Curved Rock Lock Residential Landscaping - Set of 2, then maybe they wouldn't have spent so much time and effort making Stonehenge out of rocks. In just a matter of a few, sweat-free minutes, you'll have the flowerbed or raised garden that you've always wanted. This set of round sections is crafted from high-density polyethylene (HDPE) that has the look of stone, while being light enough for you to move it by yourself. The interlocking sections are connected together, and you can fasten them to the ground when you drive in the included metal stake. Plus there are different shapes and configurations to choose from, so choose the one that works best for you.
