The items that make up this set appears to well made. Kinda of disappointed that there are no written instructions supplied. I was first please to find a dvd included, but it demonstrates a multiplying bottles routine using a tube which is not included in this trick. It appears to be the same bottle set supplies; nonetheless, the book is not shown in the demonstration nor is it part of the explanation. After you examine all that is included you can figure out the handling by using the demonstration video that is posted with the product. So I do wonder why they fully show a different approach using a tube and not the book. There is no information on where you would obtain the tube. If you were to use this set without the book I do not believe it would be much of a presentation. I would have gave it 5 stars if they included something concerning the book.
