The cube is 1.5" x 1.5" in size and is designed to hold a medium sized air plant. Air plant included. It is backed with strong magnets, so it won't slide on the magnetic surface. It can also be displayed on a desk or shelf, making this a very versatile design. The color blocking is hand painted. The magnets includes an easy to care for air plant and plant care card. Air plants enjoy being soaked in water 1x per week for 20 minutes. They also prefer bright, indirect sunlight.
