A showcase designed to display and contain precious objects and books. The result is a transparent solid that invites the gaze to linger on its contents. The shelves are rotated and bevelled, creating a displacement from a 90 ° angle to 45 ° without edges. Geometrically rotating surfaces that create 45° smoothed edges achieved by using a metal joint onto which aluminum profiles are hooked, veneered with precious wood types. The opening is totally invisible with the exception of a small key on the lateral profile.
