Wappa Lunch Box -曲げわっぱ-A Wappa lunchbox made of natural cedar that can be used in the dishwasher. This lunchbox has a gentle wooden texture and is very easy to handle. The specially ventilated coating helps protect the lunchbox and can be used like porcelain or ceramic. It also has excellent heat resistance, has great moisture control (which prevents the rice from getting "wet") and allows for the best tasting rice on the go! * Photos are for illustration purposes only.
