New, Unused Costco Big Mug Cups Nordic Style Set of 2 These were originally sold as a set of 6. We shared them with 3 families, so there are only 2 left. The colors and shape are cute, but they've been sitting in the cupboard unused. [Light Blue x Red] [Black x Red] There are original black specks and small bumps on the ceramic inside the cup. Please check photos 6 and 7. There are some black marks on the bottom. Please understand.
