What on Earth is going on here? This clever design is called the “60 Hour Candle” and, yeah, beeswax candle lasts for about 60 hours. The coil of wax burns at the rate of three-inches for every hour, or there abouts, and as it’s 180 inches long that gives you plenty of candle.
The candle is $30 and refills are $18. It tends to sell out quickly before being restocked. I’m not surprised it’s popular.
