{"product_id":"harry-potter-heat-changing-mug-marauders-map","title":"Harry Potter Heat Changing Mug - Marauders Map","description":"This Harry Potter heat changing mug is sure to cast a magic spell over your morning brew. Cold, the mug shows the password to the famous Marauder's Map - \"I solemnly swear that I am up to no good\" - and some footprints indicating the students and teachers of Hogwarts walking around the school. When hot liquid is poured in, the mug transforms to reveal Moony, Wormtail, Padfoot \u0026amp; Prong's Marauder's Map. Once the drink is finished, the password to close the map - \"Mischief Managed\" - is revealed at the bottom and the mug returns to its original state as it cools. An essential for any Harry Potter display.\\n\\nDimensions: 400ml - 12.5 (w) x 10 (h) x 9.5 (d) cm\\nPackaging: Gift box\\nComposition: Stoneware","brand":"Harry Potter","offers":[{"title":"Default Title","offer_id":39833725599818,"sku":"MUGBHP02","price":10.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0135\/4586\/5280\/files\/MUGBHP02_1.jpg?v=1781527365","url":"https:\/\/www.halfmoonbayshop.co.uk\/products\/harry-potter-heat-changing-mug-marauders-map","provider":"Half Moon Bay Shop","version":"1.0","type":"link"}
