This black Porter-Yoshida & Co. Tanker 2Way briefcase is crafted from hard wearing technical fabric with a contrast orange lining. It features a detachable shoulder strap, zip fastening, two outer pockets and zipped inner compartment. We decided to carry out an analytical examination of whether to get another of this Porter-Yoshida & Co. bag, and when it ticked every box we figured it was a no brainer. It was a brief case.
