Created by Philipp Mainzer for e15, the Stop Bookend Onyx is a super minimal desk or shelf accessory and a pure celebration of the finest onyx marble. Crafted from durable oiled onyx, each bookend is elegant and completely unique. With its cubic form and heavy weight, 'Stop' is a striking and functional object, its use is open to your individual interpretation.

Born in Germany, Philipp Mainzer studied product design at Central Saint Martins College of Art and Design, and architecture at the Architectural Association both in London. In 1995, Philipp Mainzer co-founded the modern furniture brand e15. Having established the progressive, enduring philosophy and unique branding of e15, he has received international awards for many of his designs, which are identifying icons for e15 and part of several permanent exhibitions in museums.
