To use these floating candles, simply place them in a bowl of water or your chosen candle holder. They'll add a touch of elegance to any event. Remember, the burn time is around 2 - 3 hours, but it can change depending on where you are and the climate. When it comes to storage, keep them in a cool place away from direct sunlight. Avoid leaving them in extreme heat, as it can cause the candles to melt or deform. This is especially important during shipping to hot areas. If you're planning an event, set them up close to the start time to ensure they look their best.
