The series is on three BluRay discs and comes in a box and includes a booklet. As you can see by one of the covers, the Ayakashi Bakeneko arc is included with all the regular Mononoke arcs.
(If this picture is too big, please let me know and I'll put it under the cut as well!)

The Bakeneko/Zashiki-Warashi disc.
Booklet back cover. For some reason the only item my flash decided would be good to use on. The ink on this seems to be a metallic ink, so it's slightly shiny.
The booklet has backgrounds, characters designs, and I what look like interviews. It's quite pretty.
We've only watched a bit, but the video quality looks AMAZING. The box and book are also both gorgeous. It's a very, very awesome set.
