The Toshiba Ultrabook Envelope Sleeve is a high quality, stylish portfolio case designed exclusively for the Portege Z series Ultrabook by Toshiba. The slim, form-fitting lightweight design adds almost no weight or bulk, yet protects your Ultrabook from the everyday bumps and grinds and easily fits into another carrying case for extended travel. The soft, plush microfiber interior lining feels great and helps protect your Ultrabook against scratches.
