Papercraft Square² is a cardboard life-size replica of the WWR Square² figuree that was created exclusively in the Japanese Defence Force colourway for Wonder Festival 2011 Winter. They will be available for distribution at Good Smile Company though a date has not yet been announced. Smaller scale Papercraft Square² Take Home cards were made available for free to attendees of the event.
