Mugs with colour-changing Stickers
Stickers that change colour when they are exposed to heat (for example hot drinks) are attached directly onto mugs.
How to do it
Wash and dry the mug well.
Rub the backing paper of the sticker before removing it from the foil.
Remove the foil from the paper.
Place the sticker onto the mug. Rub well from the middle and outwards to remove air bubbles. Important: the distance to the rim of the mug MUST be min. 2 cm as the stickers are not approved for food use.
Leave the mug for two hours after which it is ready for use.
The mugs can withstand mild washing by hand. They are not dishwasher safe.
