Realistic rock water/feed bowl adds a more natural look to your terrarium while providing safety and quality, too. Constructed of foamed polystyrene. Does not release dangerous toxic residues into the water. Molded stairs prevent drowning of smaller reptiles and amphibians. Smooth non-pitted, non-porous surface will not absorb bacteria, stain or leak, making it a cinch to clean. Super strong; Will not break when accidentally dropped.
