Our natural soy candles are made with soy grown in the US and fragrance oils with no phthalates, parabens, carcinogens, toxins, formaldehyde, heavy metals, or harsh chemicals. Each scent is rigorously tested to ensure an excellent hot and cold throw and our candles are tested to ensure an even melt pool with no tunneling or self-extinguishing. These dough bowls feature pure wooden wicks that crackle for a calming experience. We pride ourselves on excellent quality and top tier scents! *Wooden wick vessels have a small amount of coconut/apricot wax added for optimal burning.
