Candles are hand poured and made with 100% soy wax. We use only the highest quality of soy wax, essential oils, and fragrances. Each dough bowl is hand carved and will have unique characteristics of its own and may have knots, color variations, small saw marks, and/or irregularities. These bowl characteristics only add to the beauty and uniqueness of each bowl. All of our dough bowls are all REFILLABLE! Just use one of our refill kits for an Easy, Sustainable Refillable, Beautiful candle.
