Design and personalise your very own mug that changes colour when you add hot water!

Your Thermochromatic Mug changes colour in response to temperature fluctuation. This means that it bring reversible colour-changing properties to printed images or words.

When your mug is not in use, you won't be able to see your design beneath the black film. As soon as you add hot water to your mug, the film will disappear and your design will appear in colour on the side. Cool!


1. Thoroughly clean and dry your mug and draw your own design on the side with the pens supplier.
2. Take the black sheet and cut out a simple design to place over your drawing (e.g. a love heart).
3. Soak the cut out shape in water for a few minutes and then remove the black film from the backing.
4. Place the black film onto the mug over your previous drawing and wait until the film is dry.
5. Add hot water to make your preferred hot drink and watch your personalised design 'magically' appear!
6. It will disappear again when your drink is finished or cools down.

Hand wash only, not recommended for the dishwasher.
Recommended for ages 8 and up.
