I used these at a traditional moxibustion clinic. I also use them personally, but I have too many, so I'm selling them. Recently, my family and I have been using other old ones that were opened. They've been helpful for treating ailments and when we're in trouble. They are unused, but quite old, so I've selected "Like New." Only one box has been opened for the photos. I haven't checked all of them, but I would appreciate it if someone would take them as they are. Thank you for your consideration.
