Pure Beeswax from Fingerlime Hill is free of pesticides, herbicides and fungicides. We operate a permaculture farm and do not use chemicals in the production of our products. These beeswax tapers burn cleanly without residue. Beeswax has no expiration date. It is best to store covered in cloth and away from heat. Candles should be placed on or in a fireproof, heat resistant surface or candleholder.
