Thanko - USB rice ball warming pouch

Thanko made an innovative product for Japanese traditional food, Onigiri (Rice Ball), as a follow-up to their USB warming bento box pouch released last month.

It's a small pouch that a convenience store rice ball will fit into and will make the rice ball warm by connecting to a USB port. The case itself can warm up to 60 degrees celsius, so the rice ball becomes warm enough for eating in 15-30 minutes.
