Your chance to pledge ahead and get 5 monster girl pins at an equivalent to early bird pricing! Given that the pins will range from $20-$23 after Early Bird (the first 48hrs) are up, this is a good deal - especially if the pins you pick are unlocked after that.

During your post-campaign survey you will be asked to pick your pins. You can get duplicates. 

Pins that are available options:
-Any monster girl pin unlocked in this campaign excluding Golem
-Gorgon
-TV Cat
