Despite their tiny size, these little frogs burn quite well and people love them. They are more of a novelty candle for a collection. Beeswax burns much longer and brighter than regular toxic paraffin candles. They are hypoallergenic and non-toxic. My wax is always pure and sourced from the Canadian countryside and filtered several times over. Trim wick to 1/4 inch prior to lighting and each new time you light the candle. Never leave a candle unattended.
