Query: THIS REALLY WORKS!!!

YOu may believe me and you may not but I purchased a bag of these scented rock and did like the instructions told me and placed them in a beautiful glass bowl. MY house smells so wonderful and all I have to do is shake them up every other day. Please if you like you house to smell good stop spending all that money on candles and switch to scented rocks. And not to mention the people are wonderful and easy to work with.
