Don’t be a doughnut and keep your cup warmYou won't be a doughnut with this clever USB Cup Warmer device! Simply plug this doughnut coaster into your PC or laptop via the USB port, and it will get nice and toasty. Perfect as the ideal coaster to keep your mug of tea or coffee warm. No more forgetting about hot drinks whilst you are busy working and letting them go cold! The coaster comes in a cute doughnut design. Good enough to eat but not for human consumption though! Not only does it look good, but its pretty handy too!
