  • Building block, and wall or yard edging therefrom

On the other end of the block, the positioning of this corresponding protruding member and indentation are reversed. Thus, the bricks can be laid end to end and supported. The slots in the brick and the top step permit a strong block shape. The lip also permits a stepped portion structure to form a wall having the height of several layers of bricks or blocks.
