These solid 2x9 inch pillar candles have the dye and fragrance oil added to the wax before they are poured so they are a uniform color and scent throughout. Each 2x9 pillar candle is hand made in our factory in Central Pennsylvania. We make a variety of scented pillars and white and ivory unscented candles that will burn for approximately 60 to 70 hours. We use strong fragrances with really good scent throw so these tall pillar candles will still do a good job freshening up your home. The unscented pillar candles are great for decorating. We use braided cotton wicks in our 2 inch candles to create a beautiful burn.
