A paper box is a three-dimensional structure, formed by the movement, stacking, folding, and encircling of several planar surfaces. In the three-dimensional composition, the planes play a role in dividing space. By cutting, rotating, and folding the planes at different locations, the resulting planes convey different emotional expressions.
