Frequently Asked Questions

Q: How does the color changing coffee cup thermometer strip work?

A: The thermometer strip uses liquid crystal technology embedded in the paper material to react to heat. As the temperature of your cup changes, the strip shifts through a range of colors, each corresponding to a specific temperature between 0°C and 70°C, giving you an instant, easy-to-read visual display without any electronics or batteries needed.

Q: Will the thermometer sticker stay on my mug permanently, or can it be removed?

A: The sticker is designed for easy, firm application to cups and mugs. It adheres well to most smooth surfaces. While it is meant to remain in place for ongoing use, removal may depend on the surface of your specific mug. Take care when removing to avoid damaging the cup's finish.

Q: Is this thermometer strip safe to use on cups I drink from every day?

A: Yes! The strip is made from paper material with no high-concern chemicals listed, making it a healthy and environmentally friendly choice for daily use. It attaches to the outside of your cup and does not come into contact with your beverage.
