The 12x12 concrete stones are $20, ceramic 12x12 $15 - haven't been tested year round outside but have held up to spring rains (concrete have been left out year round through summer, fall, winter, spring), ceramic 6x6 $6 and ceramic 4x4 $5 - all pick up prices but shipping is available - drop me a line if you would like one painted up with your pet or a scene...or favorite animal... The tropical 12x12 concrete and the (3) 6x6's shown are ready to be picked up.
