This kit is produced to allow learners to create a heart themselves using dedicated clay and a heart-shaped mold, enabling hands-on learning of the heart’s structure and the principles of blood flow. By utilizing the IP of Trauma Center: Golden Hour and integrating it with the main character, Baek Kang-hyuk, the kit is designed to provide learners with a story-based immersive educational experience. This is an experiential clay kit that helps learners easily and enjoyably understand the role of the heart and the process of blood circulation.
