Norpro's mini cup warmer. How many times have you poured a cup of coffee or tea and then let it sit too long and it cools off. Once that happens, you have to; stop what you are doing, get up, trudge to the staff lounge, activate the microwave and how many times have you 'over-heated' your beverage and burned it! This cup warmer is great for maintaining a drinking temperature till you finish the entire cup. It features a lighted on/off switch, is ideal for your office, home, dorm, and travel. It is easy to clean.
