This Nickelodeon kids luggage has been designed with the unique characteristics of children in mind by Heys, as it incorporates several design features that benefit children.Aside from the vividly printed Paw Patrol characters, our designers incorporated several children-specific feature. A very lightweight design, weighing in at a mere 3.7 lbs means children and toddlers can wheel these fun cases around with ease. In addition, the unique design of this case allows the wheels to protrude out. This protrusion gives the case a higher ground clearance which allows the case to roll over obstacles. They also feature our inline skate wheels that allows for effortless rolling in different terrains. It comes with a push-button telescopic trolley handle system that can easily be pushed in and out. It has a zipper closure system, that when opened reveals a fully lined interior as well as a zippered divider for internal organization.MATERIALPolycarbonate compositeWHEELSProtruding Inline skate wheels with Metal BearingsHANDLEQuick-release Trolley Handle System
