Pillar candles are cylindrical candles that stand upright and are typically made from wax. They come in various sizes and colors, making them versatile for different settings, such as home decor, celebrations, or religious ceremonies. Unlike taper candles, which are designed to fit in candle holders, pillar candles can be placed directly on surfaces or in decorative holders. These candles can burn for several hours, depending on their size, and are often unscented or scented. Scented candles can enhance the ambiance of a room, while unscented candles are ideal for creating a soft glow without added fragrances.
