Heat up your mug, and you'll discover a very special surprise. Your family will be represented by our Tinok characters. Isn't it a hilarious idea? It's the perfect gift for leaving that person who adores drinking coffee on fire speechless, so when they put their mug in the microwave, they'll be in for a big surprise! To personalise it, choose the characters that best represent you from our Tinok family and tell us your names. We've got plenty of them so you can find the perfect one for each member of your family! This mug is also a very special mug, as it looks black when cold, but when you pour in a hot liquid, you start to see the design it hides. It's an amazing mug to surprise anyone! Important: The mug is microwave. Important to note: In case you choose to add more than 5 characters, these characters will be placed in two rows in the product. This means that: - In a family of 6 characters: There will be 3 in the top row and 3 in the bottom row. - In a family of 7 characters: There will be 4 in the top row and 3 in the bottom row. - In a family of 8 characters: There will be 4 in the top row and 4 in the bottom row. Important: This mug is NOT dishwasher safe. It may lose the black colour of the surface.
