Christmas is just around the corner, and which household with children of a certain age doesn't have a letter to Santa with one (or both) of these famous and fun toys listed? In partnership with Mattel, we've launched a special competition, giving five lucky readers the chance to win the ultimate Christmas present bundle. The bundle - worth over £450 - will include two of the must haves this Christmas from two of Mattel’s iconic brands, Hot Wheels & Barbie.The Hot Wheels City Ultimate Garage has four levels of racing, stunting and storytelling for kids to explore! Each level inspires track-play adventures – for example, the ground floor features cool track-play details like moveable hoses, a car wash with a foam roller, diverters and connectors to connect to other Hot Wheels sets (sold separately).
