Harry Potter ceramic travel mug with open and close lid in double walled stoneware holds 16 oz Platform Nine and Three-Quarters (Platform 9¾) is a platform at King's Cross Station in London. Magically concealed behind the barrier between Muggle Platforms Nine and Ten, this Platform is where Hogwarts School of Witchcraft and Wizardry students board the Hogwarts Express on 1 September, in order to attend school. In order for someone to get onto Platform Nine and Three-Quarters, they must walk directly at the apparently solid metal ticket box dividing Platforms Nine and Ten, but now you can start each day magically with this ceramic travel mug. Measures 6 x 3.5 and holds 16 oz- safe to place in the dishwasher or microwave (top off.) Top is hard plastic with open and close feature, recessed for best fit. Double walled to keep hot beverages hot and cold beverages cold. Kiln fired in my New Jersey studio- design created to enjoy a lifetime! So Accio coffee or accio tea!
