This Santa Jack belongs to the The Nightmare Before Christmas Deluxe 10 Piece Box Set by Be@rbrick - Medicom. It was sold loose. The whole set is quite big but honestly I don't collect everything from The Nightmare Before Christmas. I only collect Jack Skellington related things. I do want to get some of the other characters but Jack is my priority.
Anyways... here are the photos of Sandy Claws. The red is pretty bold. Also the you can remove Jack's beard if you feel like getting a clean cut Jack.
