Includes a pack of 20 Fragrant Frankincense and Myrrh Incense Sticks. Simply light the stick and then carefully blow out the flame. This will leave the glowing embers to smoulder and release this exotic fragrance. Each of the 20 sticks will burn for approximately 1 hour (depending upon airflow). The sticks can be carefully extinguished and then re-lit| should you require.
