Power-up with a video game legend with this Super Mario Bros. Heat Change Mug. A fun drinking mug inspired by the iconic video games, simply add a hot drink to see a classic Super Mario level screen appear before your eyes. When cold, the drinking mug displays a plain Mario level background, but when a hot drink is added the background changes colour and extra details appear, such as coins, enemies, clouds, and of course, Mario himself. A great gift for any Mario fan, the mug is inspired by the classic video games first released in the 1980s. This is a new and unused 300 ml (10 ounces) mug in an illustrated box, stored in a smoke and pet free environment. This is not suitable for dishwashers or microwave use.
