Product information
Loved this cup for the two days I was able to use it. I’m sure it states that it’s not freezer safe but I didn’t check. As you can’t really get ice into it I figured I’d just freeze some water into the bottom and the whole bottom split. Definitely a bummer as it was a beautiful cup, and I loved using it while I could.
The absolute cutest thing I've ever bought! So high quality and lightweight!
This is so cute! I can't wait to use it
It's ADORABLE. Just as I expected and cute packaging too.
This glassware is FIRE, it looks awesome, and so does the packaging.
