This is a special edition of Syndrome's [CORE Special Box][1]. This set was sold at Third Stage, after the box's initial release, and includes only the booklet, 5-pack of trading cards, and bonus disc (so the box itself is not included in this version). However, the bonus disc here is a 12cm CD-R (vs 8cm CD in the original box set) “complete version”, which features 30 minutes of band comments (which had been trimmed to only 20 minutes in the original box set, due to the 8cm CD format's size limitations). Only 50 copies of this set were sold, making it extremely rare―I've never seen this version's bonus disc.
