The interior of this bookstore is constructed with two-step sloped shelf as base shelf and sitting area for customers to sit on while reading. In addition, customer and store staff can step on the base shelf and reach the books on the top shelf. The polycarbonate is used to build the ground shelf, in order to create a certain transparency for displaying the animated toy kits. Polycarbonate is more resistance to scratches than acrylic and glass, and cost less.
