This is a set designed for high vacuum storage of food to inhibit bacterial growth for 3–5 times longer than standard storage containers. The rechargeable pump works automatically by simply pressing a button, and stops automatically when reaching a high vacuum degree of -0.03 Mpa. With FDA-approved Tritan materials, the container is extremely safe to use and can be heated in a microwave oven. It is about 70% lighter than common glass containers, and therefore convenient for packed lunches. The fully detachable design of the container allows it to be easily cleaned for long-term use.
