Designed Especially for Kids. The ''Designer Nickelodeon' collection was created by Heys with the unique characteristics of children in mind as it incorporates several design features that benefit children. These beautiful cases have Nickelodeon characters specially printed onto their hardshell surfaces. There are a variety of unique character prints in this collection; these prints include popular characters such as Dora Teenage Mutant Ninja Turtles Paw Patrol Spongebob and many more. In creating a 'High-end' series for Nickelodeon the designers incorporated several children-specific features. One of these is the internal 'reversed-curved' handle system that curves the handle inwards & upwards closer to the child making it much more comfortable for the child - at a low height - to hold and navigate the case. The Patent Pending design of this case also allows the wheels to 'protrude' out. This protrusion keeps the case elevated so that even when being rolled at a very low height off the floor the wheels will be the only point of contact and the case will continue to roll with ease. The cases weigh in at a mere 3.7 lbs and feature inline skate wheels that make their rolling even smoother so any child can easily wheel these fun cases around. They also have a zipper closure system that when opened reveals a beautifully lined interior as well as a zippered divider for internal organization.
