Create a patio instantly, without the cost of pouring concrete or installing stone pavers! Set of 6 interlocking tiles (each 11-1/2" square) look like real stone, but are actually made of durable plastic. Leveling “teeth” on the reverse of each tile grip any unpaved surface, even the hardest soil. Water drains right through for a non-slip surface in all kinds of weather! Pieces snap together and install in seconds without tools.
