Review: Love it - Doesn't leak and goes well in micro. Light weight
Review: Excellent bento boxes, leak proof, truly microwavable and light to carry - I'm really happy with these bento boxes. They have replaced the bulky/heavy glass boxes I send my kids to school with. They like warm lunch and like to microwave them. Just be aware when packing wet/moist food that they could leak into the other compartments. I also bought the small sauce containers by the same company but was disappointed with that one. Gave a one star review there. I'd recommend to read it first before buying it too like I did.
