Most of us just cannot start the day until we have sipped on our first cup of coffee – so why not drink your cup of joe from the Crossword Mug? After all, you might as well keep those brain cells going while downing caffeine, as this £4.99 purchase comes with a marker-style pen that is easy to wipe off once you’re done with your answers. The clues are located on the back of the mug, which means you’ll need to constantly turn the mug round and round before completing the entire crossword. Too bad the puzzle cannot be renewed, making this a one-time solvable gift only. Would be cool if each time hot water was poured in, the crossword would change dynamically.
