Our hand blown glass balls are beautiful and durable. Each piece is hand crafted, one at a time and can be created to match any décor or color theme you specify. The smaller orbs are blown thinner and lighter, to hang on the holiday tree. You can also display them in a shallow bowl, float in a pond, or hang in a window all year long. However, its best to order a pond floats or larger size balls for outdoor use. These are made much thicker, specially to withstand the wind and weather.
