Griffin Technology and sustainable fashion house Prophetik have teamed up to create their first product, the Folio case for iPhone 4. The Folio is a hand-stitched bifold wallet-style case, made from leather taken as byproduct from existing manufacturing processes, and featuring open access to all ports and controls and separate internal compartments for cash and cards. Griffin + Prophetik’s Folio case for iPhone 4 is available now in brown leather with red stitching or black leather with blue stitching, and sells for $60.
