I’ve taken my full universe terrarium & cut it in half, creating a flat back, so this terrarium is able to sit up against a pile of books, on a shelf, or hang on a wall. It has one pentagon shaped opening at the front & is also open at the back. It will arrive as a kit, with almost all the supplies you need to get started: pebbles, activated charcoal, & a few suggestions for how to get your terrarium started. The terrariums are handmade from glass & a lead-free silver alloy solder. This stained glass terrarium comes in silver or with a copper patina. Suitable for sitting on a flat surface or hanging in a window or on a wall.
