Hello Hetty,
That 'Mama' cup has a chip in the rim and though I didn't show it, there is a crack on the back side. I don't remember when that happened, but I really don't think it happened upon my rock. Must have been during all the moves it has made since then. But for Christmas I always fill it with holly and have it out for all to see. I'm afraid tea would leak . . .
Thank you and Happy Thanksgiving right back to you and your family.
