Rob Law pitched the Trunki children's ride-on suitcase on BBC's Dragon's Den.
Law designed Trunki as a colourful, hard-shell suitcase that children could sit on and ride through airports. The product grew from an earlier ride-on concept called the Ride-on Case, developed by Law's company, Magmatic.
Trunki is often described as a Dragon's Den success story, although the television pitch did not result in an investment. The suitcase became widely known for combining children's luggage with a ride-on design, helping distinguish it from ordinary wheeled cases.
A related point readers often ask about is the product's name: Trunki refers to the ride-on suitcase brand, while Rob Law is the entrepreneur associated with its invention and development.
