Every one is a one-of-a-kind! These handblown glass terrariums are made from recycled glass, and are individually melted onto a piece of matching driftwood. VERY unique, very stylish, and a wonderful way to display your plants, keep unwanted fingers and paws out of your plants AND keep them nice and humid! Carnivorous plants need high humidity, and air conditioning and heating systems pull the moisture out of the air to make it more comfortable for people...not a good thing for the plants. Your plants will love you for giving them the humidity they need! These small-sized terrariums are perfect for one of our Small Potted Venus Flytraps, sundews, butterworts, and other plants. Every one is different, but the glass portions average about 4 inches in diameter, and 3.5 inches tall. What a great gift idea when you combine this with a plant and a quart bag of our Standard Carnivorous Plant Soil!
