The Exo Terra Skull hides are extremely realistic and add an exiting accent to any type of terrarium, desert, rainforest or aquatic. These hides offer multiple entrances for easy access and add an extra dimension to the terrarium setup.
I could tell you that 12 times for each skull but i think 1 is enough just look at how realistic they are!
Size per skull 10 x 8 x 8cm
