Zane Marble Bookends-Set Of 2Books deserve a strong supporting cast. The Zane Marble Bookends Set of 2 brings weight, color, and natural character to your shelvesfunctional first, but never boring. Each piece is carved from green marble, so the tone and veining shift from set to set (thats the point). Clean, sculptural forms keep the look modern while the stone adds a grounded, lived in feel. A practical accent that also reads like art.
