I call these candles ritual candles but they are also called "Chimed Candles". They burn for approximately 2 hours and measure to be 4 inches x 1/4 inch in diameter. You will get 6 candles. These candles are perfect to use inside the mini cauldrons, or if you want to burn a candle while doing healing ritual or when you want to honor someone's memory. These gray candles appear to be more silver minus the metal flakes than regular gray colored. They are used for the Goddess, moon, instinct and feminine energy.
