Using these floating candles is easy. Just place them in water in a floating candle bowl, or in your preferred candle holder or candelabra. They'll add a touch of elegance to your spa, wedding, or dining table. When it comes to the burn time, expect around 2 - 3 hours, but remember that things like altitude and climate can change this. Be careful with extreme heat. If it's very hot outside or you're in a hot area, the candles might be affected. Store them in a cool place. And that's all you need to know to enjoy these lovely gold floating candles.
