I can't hardly call on a wingbone without a kisser button. You can use almost anything for a kisser button. I've seen deer horn, beads, I even made mine out of an elk tooth. Once you find the spot where you like your call to be thats where your kisser button will go. That way you can put it in your mouth and have it in the same spot everytime. I always glue my kisser buttons on with goop. JMO
