What product did Rob Law pitch on BBC's Dragon's Den under the brand name Trunki?

Rob Law pitched a children's ride-on suitcase on BBC's Dragon's Den under the brand name Trunki.

Trunki is a small, ride-on suitcase designed for children to sit on and pull or push while travelling. The product was created by British designer and entrepreneur Rob Law, who developed it as a child-friendly alternative to an ordinary piece of luggage.

The pitch became memorable because the dragons questioned the product's design, manufacturing and commercial potential. The suitcase was not simply a toy: its defining feature was that it combined children's luggage with a ride-on form for use during travel. That distinction separates Trunki from ride-on toys and from ordinary wheeled suitcases.

The product later became an established travel brand and won design recognition. A televised pitch does not by itself prove that a deal completed, so the clearest fact to retain is the product category: Trunki is a children's ride-on suitcase created by Rob Law.
