I still have an unopened tin. I purchased 36 tins about two or three years ago. I am looking at my Kava King mousepad right now.
They're not bad, but they are flavored micronized (or they may have an unflavored version). They're not an "instant" in the way that Fire Island is instant. Rather, it's really finely ground kava root mixed with a sweetener like fructose, stevia, and/or maltodextrin, and a flavor like chocolate or berry.
I'll probably buy a bag for the cute little tam tam.
