I use this tool in my Reiki practice and as a personal space. I can use this for so many things. A great way to cleanse the negative energy away from pretty much anything. I experiment and try new approaches each day and have gotten great results. With or without a practice this is a must have item, I purchased both the 4 and 9 inch sizes. The 4 inch is the perfect travel companion and can’t see myself without it. Customer service was great as always. Keep up the awesome work, appreciated!
