This is a Zojirushi lunch box. It can hold a generous amount of rice and side dishes. The rice stays warm, so you can enjoy a delicious meal. The side dish containers are like tupperware and I think they are leak-resistant. I used it about once or twice a week for about 2 years. I disposed of the case because it was old.
