Can´t find anything on Google and I didn´t buy it because I ordered the German Mediabook, but the description on Amazon says: "Boîtier Blu-ray avec fourreau" what means Blu-Ray case with slipcover. So 80% probability, that it comes with the slip.
There are some more slipcovers, that are hard to confirm: The Possessor and The Nightingale (both France). If you see pictures of them I would be pleased when you post it here or in my threads. Thanks
