A great alternative to burning candles! These beads absorb up to 30% oil and last longer than water based bead air fresheners. Aroma Beads are easy to make and will not shrink or grow mold. I really like them in my car, as a decorative accent to silk flower arrangements, inside a lace sachet, in drawers or closets or anywhere that accumulates stale air. Use with our liquid candle dyes and fragrances oils.
