The Medicom Toy Real Action Heroes Jean Kirstein figure stands at 300 mm tall with a highly detailed head sculpt that captures his determined, laconic expression. The short, dark hair is textured to look natural, and the carefully painted eyes and subtle shading enhance the lifelike feel. The figure wears the classic green Survey Corps jacket with layered vest and an accurately rendered harness. A realistic fabric cape drapes behind him, adding dynamic presence. The 3D Maneuver Gear is meticulously molded, with separate blades and intricate detailing on the straps. Interchangeable hands allow for gripping, pointing, or combat-ready poses. Premium paintwork separates leather straps from metal gear, delivering a displayable, museum-quality presence for collectors.
