The tealight candle is a self-contained, versatile little candle. It's efficient and and very inexpensive. The tealights are compression molded and set in aluminum cups with 100% cotton wicks. Our unscented tealight candles are a great value. They can be used in oil lamps (sold here), potpourri burners, food warmers or any standard glass tealight holder. Can be used everyday and burns for up to 4 hours. Size: 0.5"(H) x 1.5"(W).
