This is a pack of natural moxa for direct moxibustion, enough to fill a 12cm ziplock bag. I don't have a precise scale, so I'm not sure how many grams it is, but if you use it in rice grain-sized pieces, it will easily last for six months. I think you can see from the photos that it is of high quality with few impurities. How about it for stepping up from the Sennenkyu (Thousand Year Moxa)? The video "【保存版】初心者でも大丈夫。本格お灸入門" (Beginner's Guide: Authentic Moxibustion for Beginners) on YouTube is very helpful.
