The Mercury Water Globes offer a smart, self-regulating watering solution, ensuring that plants receive the right amount of moisture. Simply fill the globe with water, insert the long stem into the soil, and as the soil dries, the vacuum inside the globe releases water to the plant’s roots. Made entirely of glass, the set of two globes features a distinctive organic shape, combining durability with refined elegance. Perfect as a thoughtful gift, they blend functionality with style.
