Three Kings Resin Incense is a blend of Frankincense, Myrrh and Sandalwood resins. The result is a colorful blend with a delicious smell. Each bag has 1oz = 28 grams of resin.(sometimes a little more) Instruction: Light the charcoal disc and place it in the non flammable holder or bowl. Never hold the charcoal disc with your fingers. Apply flame to the sides of the charcoal disc and wait for the charcoal to ignite and warm up, this can take up to 3 minutes. Place the resin on top of the charcoal. The resin will begin to burn and release the essential oils through the smoke.
