With this fantastic novelty gift, you can easily create a personalised mug for yourself or even that special person in your life.
A fun and fast way to create your own an invisible design, which then appears as if by magic on adding hot water to the mug – then slowly disappears as the water cools.
Just follow the instructions to create a design on the white mug with the 'colour changing black sheet’ and 6 coloured pens
Suitable for ages 3 and over
