These products are suitable for storing vegetables and fruits as an alternative to the vegetable compartment. ~The following is quoted from the official HP~ Freshly store even partially used vegetables without plastic wrap Put partially used vegetables and easily spoiled fruits in the "fresh vegetable case." It's excellent for storing them deliciously without plastic wrap. The secret to storing vegetables without plastic wrap is the HCS-V filter installed on the underside of the lid of the "fresh vegetable case." It releases excess moisture in the container and suppresses condensation, which causes spoilage and decay. Vegetables stay fresh for two weeks! Vegetables stored in the "fresh vegetable case" have a higher moisture retention rate and are more vibrant in color than those stored in a conventional vegetable compartment. They maintain their condition for about two weeks. The "fresh vegetable case," which can be stacked on the shelves of the refrigerator, comes in two sizes, 2L and 4L, and can be stacked. It's also convenient to carry to the kitchen when cooking.
