Anyone know how to get this off?
My mom bought this cup from the store, but the translucent part is dead stuck on there (it’s supposed to come off. She went to the store and saw multiple of this cup, picked one up and the top come off easily, but the one in the picture was a color she liked so she got it without checking to see if the top would come off as well.)
Been trying to twist it off for about 15 minutes now and my arm hurts, it’s not even budging. Any ideas?
She doesn’t want to use tools since it may strip the top but I’m open to anything.
