My dad has a few of these. They do a very good job with the physical book, and commission their own high-quality artwork. They are quite expensive, though. They are meant for people who already love the story, will appreciate the care taken to make the book, and perhaps most importantly, have several hundred dollars of disposable income that they can drop on something which is functionally identical to something they can buy in paperback for $10.
They are, ironically, extremely impractical for actually reading.
