Rob Law pitched the children's ride-on suitcase Trunki on the UK television show Dragons' Den.
Trunki is a lightweight, colourful suitcase designed so that children can sit on it and ride while travelling. Law presented the product to the Dragons in the programme's early years, but the pitch did not result in an investment. Despite that televised rejection, Trunki became a widely recognised travel-product brand.
The case is frequently cited as an example of a business succeeding after Dragons' Den. Law continued developing and marketing the product, which won design recognition and was sold internationally.
The name can be confused with generic ride-on luggage or other children's travel brands. Trunki is the specific brand and product associated with Rob Law's pitch, not the broader category of children's suitcases.
