not copal [SEP] 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
