Our Scent-Free product is pure and naturally odorless. Wondering how to add scent to pearled candles? It’s possible to add scent by dropping compatible fragrance oils close to the wick BEFORE lighting it, but please do so at your own risk and comfort level. Never add essential oils or other fragrance oils to a burning candle as oils are highly flammable! It is the user’s responsibility for all modifications made to the candles such as colors and scents.
