I havent perform these yet, but from what I read, this material is really good.
Unfortunatly, none of these can be signed, although can easliy be borrowed, except the key bend effect. But, who cares? the first effect, for example, the coin almost never leav their view.
Teaching? Pretty good! altough some of sleights are not described well enough, or maybe because I just have NO PREVIOUS knowledge or coin sleights. But you can learn it from here, with little work.
Of course, the text is full with photos to help you. Excellent.
Hard? nah, infact, they are all easy if you can do coin sleights. I never did coin magic, now I will.
Creative, for 6.5$, its really good.
I'm sure that you will add these effects to your PK routines. I recommend getting this ebook, such a great price.
