The incense burner on the right is the one with no candle. You are looking at the back of the rock where you would light the cone incense and place it into the silver tray and slide it into the rock. Then spin the rock around so that you cannot see the opening. There is a small hole in the top of the rock where the smoke comes out of. It really does give you the appearance of a miniature volcano. Stick incense can be used by placing the stick down the hole at the top.
