A little bit about it mainly focusing on Japanese releases from hopefully a complete full-set. To a near complete packaging sample collection, Though to trial discs and not for sale items.
I'm updating nearly everyday i know i could expand on some of the posts just trying to get some content out there.
Take a look let me know if there's anything you'd like to see/change and i'll see what i can do.
