Drop. Stomp. Done! Innovative Stomp™ Edge is a fast and easy way to create tidy low borders around garden beds, paths, driveways and more. The blocks resemble natural stone, but they’re lightweight and much easier to carry and install than heavy stone or concrete pavers. Simply set them in place, step on them and the sharp beveled edge underneath cuts into grass, gravel, sand or soil. The unique shape allows you to create straight lines or curves. Set of twelve blocks; each block is 12" L x 4" W x 4-1/2" H overall. Makes a 12' border.
