And my favorite Fullslip is the Ant-Man Novamedia Edition. Great Work.
The Thing (Mondo Steelbook)
Who framed Roger Rabbit (Zavvi steelbook - original)
Big trouble in little China (Arrow steelbook)
Society (Arrow box set)
All the Raid 1 & 2 editions I have (Steelbooks, metalpak & ultimate box sets)
