Easy to Light. A SELF-LITE briquette lights immediately when touched by flame. It will even light when struck with a safety match striker surface. Briquettes stay lit, even in wind. They burn slowly and consistently for 30 minutes or more. With the recognizable burn, you always know they're working. No-Waste Design. Each SELF-LITE briquette has an unusual "star saucer" shape and holds three spoonfuls of incense as required by the Church Rubrics until every grain of incense is completely burned. Each box comes with 100 1-3/4" briquettes. Sold and Priced by the box of 100 pieces.
