The traditional ring box is redesigned into the shape of the cabinet in museums, and the ring is displayed in the cabinet as a precious exhibit. The transparent plexiglass cover is deeply embedded in the gap between the inner cabinet and the outer wall in a penetrating way. The most interesting is that the plexiglass cover is so tall that we need to raise the cover in a cautious and vertical manner every time we take the ring out, just like stealing precious treasure from the museum in the dead of night.
