Urethane River Rocks

Urethane River Rocks by McKenzie   River Rocks were created to resemble rocks worn smooth by rushing water. Create a unique display by adding these hollow rocks to your habitats or use as a stand alone base. The Urethane rocks are created from a semi-flexible urethane, reinforced with wood making them strong yet very light. Same shape and texture as the Original Rocks only lighter!
