The front is made of a clear PVC plastic with a backing that slides into place. The back has a listing for all 16 figures. The case can stand by itself or hang from a wall.
There are plenty of ways you can display you Series 4 figures, and now you have another option. The case retails for $19.99, but do make certain you read all details regarding shipping and handling.
You can find the listing on Amazon.com
