PS3 Dark Souls II JPN CE keep sealed?

[Dreamcazman]

Hi all, I've got a copy of the japanese DS2 CE coming and am tossing up whether to crack it open or keep it sealed. I've already got a copy of the game that I'm playing, so it's not necessary to play the JPN copy.

I'd like to keep it mint, but at the same time, I'd really like to check the art book and weapons out.
