This unusual modular storage system by Barcelona-based design studio BeaMalevich looks more like an avant-garde art object than a shelving unit. Created by Finnish designer Pekka Kuivamäki, Box 1-7 consists of seven cubic boxes that fit into each other like Russian nesting dolls. The boxes can be attached to seven ropes of different lengths to create many beautiful configurations. Kuivamäki’s inspiration for the piece came from a variety of artists and movements, including Kazimir Malevich, Piet Mondrian, and Donald Judd.
