Microwaves, refrigerators and dishwashers are waiting. Take it with you-if you are looking for a stylish/functional/useful bento box that suits you or your family or children, this is it. The foldable design makes it easy to store and carry, and also makes it very cool for offices and schools as well as picnics. By the way, don't worry about the mess in the bag, because we have a leak-proof cover. Large capacity + integrated space saving-three compartments: 600ml+250ml+250ml, which can even accommodate meal preparation containers when unfolded. But if folded, it will save half of the space. The thickness of 3.5cm will give you a big breakthrough. A good partner in daily life.
