What you breath IN is just as important as what you put ON your skin or IN your mouth. Tallow & beeswax burn clean, as do these standard Wooden Wicks (which come with the audible bonus of a relaxing crackle). Scented with essential oils & colored with plants & clays, these candles can safely be used for aromatherapy or massage. For best results, trim wick to ⅛” before burning & allow melt pool to extend to edges before extinguishing, especially on the initial burn. Never burn candle unattended, or on uneven or flammable surfaces.
