The Wonder Festival isn't only about cosplay . Rather, the event is dedicated to figurines and models. So of them are production models, which are mass-produced, while other pieces are limited edition or even one-off pieces.
This year's Wonder Festival was held at the Makuhari Messe in Chiba, Japan. Sister site Kotaku Japan and figure site Moeyo.com were both on hand to check it out. Their photos are viewable in the above gallery. More in the links below.
