Kendama: The Iconic Japanese Cup and Ball Game!

I picked this book up because I had only just bought my first kendama. I enjoyed reading the book and found it valuable. But it is very brief, and not worth more than a dollar or two. and it's really missing some things that should be in even a book for this much of a beginner.I've only been using the kendama for 2 months, and I feel like in just a couple of hours I could write a better book than this. maybe I will.
