I've seen these before. You place a pod inside the pot and pour hot water or heat it up first like in the pic, then watch the pod grow into a flower and then you drink it. Pretty cool but it kind of freaks me out for some reason.
This set includes one glass teapot Juliet and one cozy tea warmer. The Juliet Teapot makes tea drinking an unforgettable experience with its crystal clear high quality glass that allows tea lovers to watch each bloom unfold.
