of very good quality terra, robust and easy to assemble. With a minimum of common sense, logic and intelligence have come to mount this terrarium in less than 20 minutes. I own three of these and they are great! I recommend a coat of varnish to kitchen and bathroom inside and outside which will protect the terra. The referred are easy to place thanks to pre-drilled holes and finishes with black chopsticks make good. I recommend it to all terrarium.
