One glass doesn’t exactly turn black but turns grey, it’s not like the one advertised.
Thank you for taking the time to write a review.
We are sorry to hear that the color of the glass is gray instead of black, we apologize for the inconvenience.
We have just sent an email to you.
Please let me check the condition of the glass first and we can discuss how to proceed.
Thank you for your cooperation.
This is a milk glass to enjoy the cute animals.
The cute animals appear at temperatures below 17°C and disappear at room temperature.
You'll be surprised at the beautiful change in design when you pour a cold drink into it.

Do not use a scrubbing brush. If the color does not change to white when the bottle returns to room temperature, soak it in warm water.
