Using these floating candles is easy. Just place them in a glass bowl or a suitable container filled with water. Light the wick, and enjoy the warm glow. Remember, the burn time can change depending on where you are and the climate. So, don't be surprised if it's a bit different from the approximate 1 - 2 hours. When it comes to storage, keep them in a cool place. Extreme heat can damage the candles, so if you're in a hot area or having them shipped to a hot state, take extra care. Also, when you're done using them, you can simply blow out the flame and reuse them later. With proper care, these candles will keep adding a touch of elegance to your events and spaces.
