This glass meal prep container set includes 5 containers of 34 oz. and 5 containers of 13 oz. making it well-suited for meal prepping. It allows users to cook meals ahead of time, freeze them for later use, and thus save time on daily cooking. The containers are made from premium borosilicate glass, a material that is stronger than standard glass food storage containers. This strength enables the glass containers to move smoothly from the refrigerator to the microwave, oven, and then directly to the table, meeting different needs for heating and serving food without any performance issues. The set is equipped with snap lock lids that have silicone seals, creating an airtight seal. This airtight design helps prepped meals stay fresh much longer than those stored in regular plastic food storage containers, and it also prevents leaks that could cause messes. The snap lock lids are easy to handle and durable. They do not break easily and will not stop working over time. In terms of usability, the set is user-friendly. The glass containers can be used in the microwave, freezer, dishwasher, and oven, providing flexibility in storing, heating, and cleaning food. However, the plastic lids cannot be placed in the microwave or oven, which helps maintain the lids’ condition. Color: Gray.
