Pujapa stick incense is made of a slim bamboo stick surrounded by ground bamboo called “punk”. When you light the stick, do not blow out the flame until you see the glow of the ember on the stick itself, otherwise, it may not stay lit. Sometimes, sticks just do not cooperate. If you have found yourself with a bunch of dud sticks, please contact us if you purchased it from pujapa.in. If you picked it up and one of our fabulous retail partners, please return it to them and we will work with them to make it right.
