Pillar candles are a type of long, slender candle that stands upright when lit. They typically have a cylindrical shape and are designed to burn evenly from top to bottom, with no wick extensions necessary. These candles come in various sizes, ranging from small votive-sized pillars to larger ones suitable for table centerpieces or decorative arrangements. Due to their design, they can provide a warm ambiance and create a relaxing atmosphere when used as accent pieces in homes, restaurants, hotels, or other venues.
