The Hanging Glass Terrarium showcases candles, air plants, moss or fresh flower blossoms, and complement simply decorated areas. This glass orb is 5in wide and 7in tall, with a glass hook on the bottom and on the top. Hook multiple glass globes together! Each globe has two openings - a main opening so that you can insert a candle or miniature plant, and another to allow for air circulation. Customers often report that these globes are larger than anticipated (they're about the size of a large grapefruit) - so if you're looking for a smaller size, we do have several other sizes with single hooks. However, this is the only size double hook terrarium available at this time. In our testing, we were able to hook 12 globes together from ceiling to floor with standard 8' ceilings. Please exercise caution when hanging multiple globes together and keep in mind that the heavier the object within the globes, the fewer you should hook together. Candles are sold separately.
