          Heavy and secure when used as retaining wall.
          I needed a quick and easy-to-install retaining wall that did not need a concrete base. These worked well when mixed with different colors. I did not need to cement or glue the retaining wall stones but I did need to cut and glue the caps on top of them

            Title is fine
            The blocks are grossly over priced. At $17 dollars a block there are many other blocks at less then half the price that will do the job.
