This product is made with at least 20% sustainable materials by weight. CHARLES & KEITH uses recycled, degradable, organic, and water-based materials in our eco-conscious collection.You will want to keep the Lark shoulder bag by your side. Subtle details enhance the sleek shape -- the crinkle-effect texture gives the grey finish an edgy feel that complements the silver-toned hardware and notched cut-outs. In the functional sense, this bag will fit the essentials while being compact enough to tuck under the arm. It also comes equipped with an adjustable strap that can convert it from a shoulder bag to a crossbody bag when attached.
