Mitsukoshi Isetan Original Cooler Bag, Pouch, and Pen Case Set This is a set of three items: a cooler bag, a pouch, and a pen case. These are novelty items you can receive when shopping at Mitsukoshi. They are new and unused, having been stored at home, so I am offering them for sale. Material: Polyester I think they are a good size for storing a few important items. The MITSUKOSHI mark is subtle, so I think it's stylish. Thank you for considering purchasing.
