The 4-liter food storage container is the largest storage container. You can use it to store watermelon, vegetables, fruits, and baked goods, and the whole family's food on a trip. Its high-quality material does not absorb odors or colors and is BPA-free. It is suitable for use in the freezer and microwave. Having the same length and width dimensions as the 3-liter container, they can be stacked exactly on top of each other to save space.
