This is a set of two boxes of Koken-To's basic carbon rods, 3000 series. They are mainly used for health promotion, skin diseases, immune disorders, etc. They are also easy to combine with carbon rods of other numbers. There are no breaks. I will pack them with double layers of bubble wrap, but please understand that they may break during shipping. *Please note that if I am listing the same item, the images may not be of the actual product.
