Freezer Grade Dumpling Box Home Use Food Preservation Freezing Box Professional Storage Container for Refrigerator

The box is nice, but it can be a bit tricky to close.

The quality of the dumpling box is really great; it's thick and seals tightly. It's much better than the ones with handles, which have bigger gaps that let air in, causing dumplings and wontons to dry out and crack. I love this one with a layer and a lid; it's so much easier to grab. I'll definitely buy it again if I need more!
