Cup glass thermal Hogwarts Harry Potter

Look at that last cup!! Is a cup of glass of almost 400 ml , with the shield of the mythical school of magic and wizardry Hogwarts that you will know of the saga of books and movies Harry Potter.

Already if it is an elegant drink that comes in a box with a window specially designed for her, which makes it a magnificent object, collection or gift.

But it is also what will leave you stunned is its reaction to temperature changes! When it is at room temperature, the shield is black and white, but as soon as you put a little bit of beer to cool the shield comes to life and is full of color!!

A great thermometer so you know when to point your butter beer in the Flying Cauldron.
