Use this stylish case made from cork to protect your iPhone from scratches. Cork, which is naturally impermeable, offers great protection for your phone & is a sustainable material. Cork comes from the bark of the Cork Oak (Quercus suber) & is stripped from the trunk every 10 years. The trees live for around 200 years & cork oak forests are home to various endangered species. David Nash has worked with cork for the first time for his exibition at Kew.
