Peek into a reptile's private burrowing world! Bark Bends provide the private den all burrowing reptiles crave, while also offering a window on their fascinating behavior. Set the open sides of a Bark Bend against the side of the terrarium glass for an unobstructed view of burrowing, shedding and nesting. The exterior is hand crafted to look natural and blend in easily with both aquatic and terrestrial habitats. A non-porous synthetic finish won't rot like real wood, and cleans quickly with warm water.
