Frequently Asked Questions
Do these cups really change color?
Yes! These cups use a thermochromic ink that activates when hot or cold liquid is poured into the mug or pint glass, respectively. As your cup fills up with your hot/cold beverage, the logos will change color or the rest of the design will appear!
Are there any special instructions when using/taking care of the cup?
- Not Microwave or Dishwasher Safe! - Due to the sensitive nature of the color changing print
- Hand Wash ONLY - Gently wash outside of the cup with soft sponge or simply with just water and soapsuds to preserve color changing print. Avoid using tough or rough cleaning tools on outside of the cup.
- Wash Before First Use
- Avoid scratching the cup with sharp objects or picking at design to help maintain color changing design
- Please Be Careful When Hot
How hot does the liquid need to be for the mug to change colors?
The hotter the temperature, the better the effect. Boiling water for your coffee, tea, or hot chocolate is most ideal.
I have heard that the color changing print on these types of mugs are not long-lasting. Is that true?
No, the color changing print will last for a long time as well as taken care of properly. Do not put into the microwave or dishwasher. Avoid scratching or picking at the design to help maintain color changing print. Wash outside of mug gently.
Am I supposed to see parts of the design underneath the black ink?
Yes, you may faintly see parts of the design underneath the black ink (before color change) if examining the mug close up at certain angles and lighting. This was by done by design to ensure the after color changing design did not end up too dark. When looking at the mug from a reasonable distance away you will not see the design underneath the black ink before color change is initiated.
Can I heat up drinks in this mug in the microwave?
No. Avoid putting these mugs into the microwave due to the sensitve nature of the color changing design. Instead, boil water for your drinks or heat up your beverage separately and then pour into the mug.
Can I wash these cups in the dishwasher?
No. Avoid putting these cups into the dishwasher due to the sensitive nature of the color changing print. Instead, gently wash the outside of the cup with a soft sponge or simply with just water and soapsuds to preserve the color changing print. Avoid using tough or rough cleaning tools on outside of the cup.
How should I wash these cups?
Will the mug that I receive look like the pictures online?
Yes! Once the mug changes color we make sure that all of our pictures are accurately representing the color change.
How cold does the liquid need to be for the pint glass to change colors?
The colder the temperature, the better the effect. An ice cold beverage is most ideal. Adding ice cubes can also enhance the color changing effect.
Will design lettering still be visible after the cup changes color?
Yes, silhouette lettering will still be slightly visible due to the difference in color shade of the regular printed ink vs the color changing ink
Why does the pint glass design sometime change color without cold liquid poured into it?
This may occur due to a cold room temperature. Rinse with warm water to change back to beginning stage (white/clear-ish logo)
