I have given away the whiskey stones as gifts along with a whiskey and personalized whiskey glasses. Because I was so cool I've also equal to a pack ordered. However, I find the cooling effect ernüchternt and stones (could also have come before it) tumble quite loud in the glass back and forth while drinking. Always the concern that I have my beautiful damaging expensive whiskey glasses. The use of these stones remains for me so questionable especially since you whiskey actually not cool .. as a gift supplement it was but still great and the stones themselves are super processed and come in a beautiful fabric bag. Perhaps there is also another benefit :)
