This is a favorite for me!!!! Once you burn these candles, you will keep coming back!! For nearly 40 years they have been family owned and operated. They burn over 110 hours! All of these 24oz. candles are made in house, & all of these products are independently tested at a lab to ensure the highest quality. American Soybean WaxTM burns pure, & it burns longer than paraffin. It is made from a naturally renewable source. The oil content is the maximum possible so that the wax will allow for soot free burning. This all natural wax out performs petroleum-based paraffin in every way.
