With this one set, you can heat in the microwave, cook, and store in the freezer or refrigerator!! The containers are sturdy with a thick design and easy-to-use sizes, making them useful in various situations. It has a unique steam vent (air cap), allowing you to heat frozen rice directly in the microwave. The 300ml size is perfect for frozen rice, holding one serving of rice in a compact size! The material and tabs allow the lid to be easily opened even when frozen. The soft seal part of the lid has a silicone ring that can be removed and washed. If you close the lid tightly, liquids are less likely to leak. The shape of the knob makes it easy to take out of the refrigerator. It's also easy to take out when hot after microwaving.
