This is a HEAT/3way business bag & briefcase from Porter (Yoshida & Co.), which is no longer in production. It's made of black ballistic nylon. I used it for commuting, but I'm selling it because I no longer need it. It has two shoulder straps stored in the back storage compartment, allowing it to be used as a backpack. There are scratches on the Yoshida & Co. logo, and a 1.5cm repair on the handle. Only the items in the photos are included; the shoulder strap and the small light that deteriorated and was removed are not included. Dimensions: 42cm wide, 30.5cm high, 12cm deep, weight 1.6kg.
