this review title is: not copal and the content is: this is not copal i have traveled to the yucatan and purchased both rock resin form of copal and a more convenient version in stick form the hard resin form must have a secondary ignition source constantly present like charcoal in order to burn the hand crafted stick version burns upon ignition just like any other stick incensethis particular product is a stick incense labeled as copal but it is not perhaps it is a mixture that contains trace amounts of copal if so they are undetectable to my sense of smell in other words do not purchase this product if you are looking for a stick incense version of copal that is traditionally burned throughout the yucatanbusiness wise great seller quick delivery etc product is misleading and incorrect.there are other information for this review, one is this reviewer did purchase it and the other is 1 people think this review is helpful.
