Question 1

Do these cups really change color?

Accepted Answer

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!

Question 2

Are there any special instructions when using/taking care of the cup?

Accepted Answer

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

Question 3

How hot does the liquid need to be for the mug to change colors?

Accepted Answer

The hotter the temperature, the better the effect. Boiling water for your coffee, tea, or hot chocolate is most ideal.     Hot liquid needs to be a minimum temperature of 49°C/120°F in order for mug to change colors
 Recommended temperature is around boiling point or 71°C/160°F for optimal color changing

Question 4

How cold does the liquid need to be for the pint glass to change colors?

Accepted Answer

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.     Cold liquid needs to be a maximum temperature of 10°C/50°F (cold tap water) in order for glass to change colors
 Recommended temperature is around freezing level -6.67°C/20°F (ice cold water) for optimal color changing

Question 5

Am I supposed to see parts of the design underneath the black ink?

Accepted Answer

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.

Question 6

Will design lettering still be visible after the cup changes color?

Accepted Answer

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

Question 7

I have heard that the color changing print on these types of mugs are not long-lasting. Is that true?

Accepted Answer

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.

Question 8

Will the mug that I receive look like the pictures online?

Accepted Answer

Yes! Once the mug changes color we make sure that all of our pictures are accurately representing the color change.   Sidenote - there are other color changing mugs online that do not entirely match the final product you receive because their product pictures will inaccurately depict the after color change design color, when in fact the mug you receive will be slightly darker once it changes color due to a color changing residue.

Question 9

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)
