(When Stored) Approximately H18 x W22 x D4.5cm (When in Use) Approximately H30 x W45 x D18cm Capacity: 23L Weight: 410g Material: Polyester Large capacity 23L size! Perfect for travel with a Boston bag, or for carrying souvenirs purchased while shopping when paired with a suitcase. 23L is a guideline capacity for 1-2 nights' worth of luggage. This is a very convenient Boston bag that can be carried small and used large! It's very convenient to fold it up and put it in your suitcase, and then use it to carry souvenirs on your return trip. It is not new, so there are small scratches. Please check the images. I think this is a design that is no longer sold.
