This is a mug warmer imported from America. By plugging it in and placing a coffee mug (or other suitable container) on the surface, you can keep your drink warm at all times. Whether you're working, studying, busy in the morning, or relaxing with a book or TV, you can enjoy your coffee without worrying about it getting cold, and without having to go to the microwave repeatedly! This is a highly recommended item! Retail Price: 3,880 yen ● Condition: Used only a couple of times after purchase. I'm selling it because I received another one. Power tested and cleaned with alkaline electrolytic water sheets♪ ● Scratches: Slight, inconspicuous scratches on the bottom. ● Box/Instructions: None
