A product branded "ridiculous" on Dragons' Den is now sold across the world and arguably one of the most successful seen on the show.
The Magic Whiteboard, a roll of A1 whiteboard sheets that stick on anything due to static, was pitched by married couple Neil and Laura Westwood in 2008.
The pair were seeking an investment for £100,000 for a 15 percent equity stake in their company, as reported by the Daily Express.
