Together with Tokushima's furniture maker "TSUBOI KOGEI," we produced wooden stationery boxes "MAG CONTAINER," constructed with built-in magnets. Each box is an equilateral triangle, a square, and a rhombus. Each has angles of multiples of 30 degrees. By combining and customizing these boxes freely, a geometric pattern is created like a puzzle and enjoyed as a room interior. By creating products smaller in size than traditional box furniture such as chest drawers, mirrors, and altars, we aimed to expand the possibilities of box furniture technology cultivated in Tokushima.
