The Zhuang consists of two round and oval stackable boxes covered by a saddle leather lid. Each consists of four trays that can be pulled out one by one, held together by a base of brushed aluminum in matte natural brass. The collection is complemented by two large trays in the same shape and a set of three office accessories: a multifunctional holder, a pen holder with ruler and a work pad. All containers in the Zhuang collection are made of solid Canaletto walnut, carved from a single piece using numerically controlled machines and finished with Cuoio Saddle Extra leather strap in Carbone, Cammello or Tortora colors. The saddle leather is decorated with extra-fine stitching with slightly contrasting yarn and the branded Poltrona Frau logo.
