Plant on a Slant's potted plant level is made up of two round wedges, a top wedge and a bottom wedge, each with a series of guide numbers (0 through 10) printed along the outer rim.
The wedges rotate on each other, allowing you to adjust the plant level to different thicknesses and therefore provide a level surface for your pots and garden ornaments. The plant level can be adjusted for any sloped area around the home, such as a driveway, walkway, patio, home entrance, or lawn.
