Dr Jekyll and Mr Hyde Bookcase is a bookcase designed by Piero Lissoni for the Italian brand Glas Italia. The former bookcase is made of 5 mm thick, laminated and thermos-welded glass. The bookcase is available in three different sizes, two narrow versions and a smaller and wider one in transparent, frosted, or opaque glass. Dr Jekyll and Mr Hyde is a playful range of storage fixtures that can be combined in groups or placed on their own.
