These are super cute and the magnets are very strong.  They work great for marking my kids' water glasses so they can stay on the counter throughout the day and I don't have to wash a zillion glasses at the end of the day.  My only criticism is that the magnets that go on the inside of the glass to hold the emoji markers in place are so tiny they are hard to handle, easy to drop, and I imagine will be easy to lose.
