GreenTree Home Candles are dedicated to high-quality craftsmanship and healthy, sustainable materials that support the community and planet. We chose this company for not only their attention to design detail of each candle, but for their commitment to sustainable craftsmanship and work practices. The beeswax is sourced in their region, the studio uses minimal energy and natural resources, and in choosing beeswax over soy or other candle materials, they create candles that release negative ions when burned, which actually help clean and improve indoor air quality. They are the best type of candle to buy.
