The Pill is the quintessential large-size, fully contained terrarium container. With a ceramic base that is 5 inches high, it allows you to build the perfect terrarium with a drainage layer of rocks, topped with charcoal and soil so you can plant 4-5 inch succulents. The glass dome rest between a lip on the rim of the base so you don't have to worry about it sliding off. The height of the dome means you can plant tall ferns and other such plants. And then everything else is left to your creative imagination. Toss in living or preserved moss, air plants, bark, rocks, quartz, little Lego dudes, then pop on the lid and let nature takes its course.
