Using these floating candles is easy. Just place them in water in a floating candle bowl, a vase, or any suitable container. They can also be used in regular candle holders and candelabras. When using, keep in mind that the burn time is around 2 - 3 hours, but it might change depending on where you are and the climate. As for storage, try to keep them in a cool place. Avoid leaving them in extreme heat, as this can damage the candles. Also, when shipping to a hot area, there's a chance the candles could be affected, so be aware of that before you buy. With proper use and care, these candles will add a lovely touch to your events and spaces.
