武神館武道伝承書 5: 真伝不動流大剣体術 カールステン・クーン著

The books in this set are an excellent resource for Bujinkan training. The only problem that I sometimes have with them is that I believe they are written in German and then translated into English, which sometimes leaves some ambiguity in the descriptions. Highly recommend though!

I received the books I ordered in the expected condition. New and properly packaged.
