When Volume XXXI (Turkey Day Collection) was released, Shout! Factory offered a cardboard slipcase as an ‘extra’ if you requested one. Since the set was released in a tin box, it was a nice option to have but unfortunately I neglected to get one and it is no longer available (I checked).
Here was the link you could request one through:
Just reaching out to my fellow MSTies to see if anyone has an extra they wouldn’t mind parting with?
I didn’t know it was an option either! Funny though, I just happen to be watching Jungle Goddess tonight. And yes, I started it before I saw this thread.
