Rob Law pitched the reusable children's suitcase Trunki on Dragons' Den.
Law developed Trunki as a ride-on suitcase designed for children. The product was intended to make travel more engaging for young passengers while functioning as practical hand luggage. Its distinctive shape and bright colours helped it become a recognisable travel product.
The Dragons' Den pitch is often remembered because the proposal did not result in an investment. Law's appearance illustrates an important feature of the programme: receiving no deal on camera does not necessarily prevent a product from succeeding commercially.
Trunki later became an internationally sold brand, and Law continued to be associated with its design and development. The business should not be confused with other British invention stories from the programme, particularly pitches involving household gadgets or food products.
