There's not much I can add in a review that hasn't already been said by the others, except that it looks far better in person than it does in the pictures and videos.

My only possible complaint might be that the simulated edges of "pages" on the presentation box seem a bit too white, and might have used a very light stain to a colour more like aged parchment, but that's only a very, very minor nit-pick, and the case still looks great without it.

The hardware seems to be steel, and it's fastened to the cover with screws, making the construction quite sturdy. The clasp is a perfect fit - neither too loose, nor too snug.

The apparently fake leather of the box and book looks and feels quite real, and it's very soft and comfortable to the touch. This may be the nicest cover material of any book in my small collection. The spine of the box and book are textured as if the contents were bound with a heavy cord under the leather (though I don't think that's actually the case, rather just a simulation.)

The inside of the box cover seems to be a very heavy, high-quality paper, and the box itself is lined with a nice, black cloth, with a dark red ribbon which makes lifting the contents out of the box easier. The inside dimensions of the box are just right for holding your typical RPG book, or the Pathfinder DM screen and one or more Flip Maps, for example. (As others noted, if it's not holding the special edition RotRl book, it would make a fine box to store a DM's screen, dice, paper, and other such materials in.)

The book is printed in vivid colour in high-quality detail on heavy paper. This is the first time I've seen a Pathfinder adventure path of any sort, but I would have to imagine this is much higher quality printing than the original. The artwork is quite beautiful, meeting or exceeding Paizo's usual standards, the text is crisp and easy to read, and everything seems quite well-organized and easy to follow. The adventure is quite detailed (there is, perhaps, almost too much detail: the information provided is quite dense). The binding seems quite secure and well-done - this book seems to be designed for the long-haul (I can't really say the same for any of my other game books.)

The detachable hand-outs are quite a nice touch, though perhaps not really practical for real-life gaming, as I would imagine it could be quite easy to abuse the book by removing and replacing the handouts until things get dog-eared and distressed. Indeed, I would have to say that the book is best used for display as a collector-item only, rather than used on a real-world game table.

The high-quality art prints are another nice touch and could also be used as hand-outs or visual aids, though these seem more like bonus material than an integral part of the adventure path. Each print is protected in its own high-quality translucent paper (not plastic) envelope for protection, and yes the prints do seem to be nice enough to frame if you are so inclined.

I've shelved the book on my bookshelf next to the special edition of The Other Guys' fake-leather-bound special-edition 3.5E core rulebooks; the fit right in with each other, though I'd say that Paizo's product is much nicer than the Other Guys' special edition books.

The whole package seems to me to be worth the price, and I'm sure it will hold its value quite well for the future. Paizo have gone above and beyond on this product, and they've earned 5/5 stars for it.
