The term KAMIKARA originates from a combination of two Japanese words kami (paper) and karakuri (mechanical mechanism), defined by renowned Japanese paper engineer Haruki Nakamura. Each kit is intuitively designed and easy to build without requiring any tools. Kit includes perforated paper sheets, rubber band, and English pictorial instructions. Once the paper pieces are popped out, each of them that require folds are scored for easy assembly. A paper hook tool is included in the kit to assist installing the rubber band. To setup the paper action, first flatten the squid and lock it by the stopper on its back. Once setup and standing, tip it over by pushing lightly on its head and see it perform a back flip and make a perfect stick landing! Enjoy the next generation of paper crafts!
