This lock and lock container has a capacity of 800ml and is rectangular, allowing for rounder foods such as sandwiches to fit into it. The container is also 100% air, liquid, and moisture tight meaning that no liquids will spill out and any food will not go off. The four flexible silicone seals ensure precision lid fitting. A benefit of this container is that there are large hinges for easy opening and closing movements. This container is also safe to use in the microwave and can be placed in the fridge and freezer.
