These beautiful oil candles are individually handmade in Arkansas and contain non-flammable clear unscented paraffin oil. The fern greens are natural; the berries and stems are handmade. Each candle comes with a fiberglass wick and a small funnel for ease of refilling. Each candle burns approximately one (1) ounce of oil every four (4) hours, with the wick positioned at one-sixteenth of an inch (1/16") above its glass tube holder. Instructions included.
