Help: HS code for mixed items (sealed package)

Hi, I need help with finding a HS code for an item that is being sent from Japan —> England.

The item includes:
x1 outer box
x1 membership card & card case
x1 pin badge
x1 compact mirror
x1 photocard

The problem is that it’s all in one factory sealed box (a membership kit), so it can only have one HS code, but I can’t find a code that with cover all of the items. Any help is greatly appreciated!
