This luggage trolley is lightweight and portable so it can be taken anywhere, from the airport to sleepovers. The dual-purpose bag transforms from a suitcase to a backpack with a simple snap on/off feature. The easy-to-manage bags, made of 100-percent polyester and with black interior lining, are washable and will keep their soft fabric. Some bags, such as this one, come with detachable dolls. Suitcase size is 14” x 11” x 4” and backpack size is 11” x 7” x 4”. Launch date: July 2007.
