Colour change cup- the specks on the cup change colour with cool liquid. This is a cold cup- don’t use hot or boiling hot liquids
You can choose to take the cup as it is, made with permanent vinyl. Or have a name put on it to personalize. Or have resin on it to seal the vinyl and make the cup smooth, or even have a name put on it AND have resin over it.
If you choose the resin option, please give me up to 1 week to make the cup and have it cure.
