Halloween "Blood of my Enemies" Magic Mug (11 oz.)
Maybe you're looking for a great novelty gift for Halloween. Or maybe you just want people to know they shouldn't mess with you. We don't judge. 🙂
This ceramic "magic mug" is plain black when empty. When a hot liquid (such as tea) is added, the message appears. Mug holds 11 oz., perfect for a large cup of tea.
