Using these candles is easy. Just place them in a glass bowl or other container filled with water. They'll float nicely and add a lovely touch to your decor. Remember, the burn time is about 1 - 2 hours, but it can vary with altitude and climate. When it comes to storage, keep them in a cool place. Avoid leaving them in extreme heat, as this can damage the candles. Also, if you're ordering and shipping to a hot area, take the heat into account. With proper care, these candles will serve you well for many decorative occasions.
