Designed Especially for Kids. The Unicorn collection was created by Heys with the unique characteristics of children in mind, as it incorporates several design features that benefit children. They can take this colorful and lightweight luggage everywhere, packed with all their special items for school, their next sports practice, play dates, field trips, or as the perfect carry-on for the next family vacation. Made from lightweight and durable ABS/polycarbonate composite, with an overall protective layer of clear coat, giving each luggage a beautiful glossy shine with vibrant colors. The colorful interior is fully lined and has double interlocking straps to hold items in place, and a zippered divider for internal organization.
