A miniature 1990s Korean primary school classroom built inside an open two-tier metal pencil case, photographed in macro on a wooden school desk. The lid stands open upright and its inner face is the blackboard, plain dark green and empty; the lower tier is the classroom floor with rows of tiny wooden desks and chairs, and the hinged upper tray, swung out to the side, becomes the hallway with a row of tiny shoe cubbies. A teacher stands at the front, small pupils sit at the desks, one raising a hand. Real pencils and an eraser lie beside the case at giant scale. The pencil case stays completely real: painted tin with scratches and a magnetic catch, its outside decorated with plain simple shapes only. Tilt-shift miniature effect, soft window light. No text, no letters, the blackboard blank.
