Base is metal with a dark gray powder coat finish, ball feet, plastic liner, and inner rims for glass house to rest upon. Once planted glass top will meet soil/moss to create your enclosed garden.
Just a really pretty small terrarium. I absolutely love it. I do have to agree with the reviewer who thought the base was a little too shallow, but otherwise wonderful.
Very attractive small terrarium!
I bought this terrarium for my desk at work. It is solidly made and simple, which I like, because it doesn't detract from the plants inside.
I do have one complaint: the bottom is too shallow for even a baby maidenhair fern. It needs at least another inch to accommodate the necessary gravel, charcoal and soil.
