EXCLUSIVE AT NET-A-PORTER. Anya Hindmarch's 'I Am A Plastic Bag' collection is designed around a sustainable canvas material that took two years to develop and has no carbon footprint. Part of the responsible range, this phone case has been made in Italy from the recycled plastic bottle-turned-fabric and has a water-resistant coating cleverly extracted from recycled windshields. The slim silhouette has compartments on either side to stow your cell and cards. Detach the leather strap to slip it into a larger tote.
