This is a great coffee mug! I put this together after getting upset that I had to change all my clocks and upset that I lost an hour of sleep which really messed with my body clock. This is your chance to let our politicians know that we have had enough (Click to Buy). We no longer need to change our clocks. This antiquated undertaking each year has outlived its usefulness. We don’t use candles to light our homes anymore. And, we don’t live on farms. In addition, we live in a 24 hour society for the most part. Changing the time saves no money in the end which was its purpose in the beginning. Just click here to get your coffee mug today! This mug is black on the outside when cold. When you pour coffee into it, the artwork is revealed. Friends will love it!
