For those who find that they eat rice balls on the regular, this novel food warmer from Thanko is a handy device to have at your desk. Whether you've prepared a rice ball at home or bought one that's since gone cold, the Onigiri Warmer with USB offers a handy way to enjoy a hot meal.

On the inside of the cloth pouch is a metallic foil and a warming contact points on each side, so in total, it takes about 30 minutes for an onigiri to be heated to the perfect temperature. When the cloth pouch is disconnected from all of the wires, it also doubles as a pretty great carrying case to transport wrapped rice balls to and from work without need for an additional lunch bag.
