Being interested in origami boxes, and seeing the low $5.95 price for this book, I bought it. I am not at all disappointed. It teaches 18 boxes w/variations, ranging from very easy to intermediate level.
For beginners, Rick teaches the Nik-Nak Box (from 8.5"x11" paper), The Printer's Box and Harbin's Box-In-One ( a small square box with a lid from one piece of paper). He moves on to the A4 Thin Box (again, from an 8.5"x11" paper), which is a long skinny box with a lid, all from one piece of paper. From there he moves on to teach Boxes w/Lids, Boxes w/Dividers, the Flower Box, a Shell Shaped Box, a Heart Shaped Box, the Peace Crane Box, a Triangle Box with a Rose on top, and my latest favorite, due to its simplicity, the "Pacchetto Regalo box", one that closes onto itself and locks, all from one paper piece. He finishes the book by teaching a 5-sided box, complete with 3 lid variations. All in all, this book is a deal for the small amount of $$$ it costs.
