Which Dragon was associated with the British stationery retailer Ryman?

Theo Paphitis was associated with the British stationery retailer Ryman.

Paphitis acquired Ryman, a high-street stationery chain, in the 1990s and expanded his retail interests through further acquisitions and investments. His business career helped establish the commercial and retail perspective he brought to Dragons' Den.

On the programme, Paphitis became known for examining practical sales potential, customer demand and the ability of a business to grow. His retail background made him especially recognisable when contestants presented consumer products or shop-based ideas.

Ryman is sometimes confused with other brands linked to Paphitis, including Robert Dyas and Boux Avenue. Those companies are part of the wider story of his retail career, but the specific stationery association in this question is Ryman.
