Their flagship flame has the look, feel, and dance of its carbon-based muse without the mess or worry. It's so realistic that you may try to blow it out at least once. The secret is an uneven cadence that rarely repeats for a wildly fluid motion. Hand-poured and crafted using 100% refined paraffin wax, the candles have an unparalleled sense of authenticity. An advanced 5-function remote control (available separately) adds multiple timer, brightness, and flame movement adjustments. Outdoor versions are also available.
