Review on MAXSO 2 Pack Insulated Food Jar Hot Food Containers for Lunch School Soup Thermos For Kids, Travel Food Flask Hot Cold (24oz, 17oz) (Grey) by Mitch Emmel

Bought these containers for my son's school lunch. The container keeps food warm until lunchtime. Pour boiling water into a container to heat it first helps a lot. Then drain the water and replace with hot contents. We have 2 problems with this container: 1. The plastic ring/seal pops out too easily when opening the container. I'm surprised my son hasn't lost it yet. Without the plastic ring, the container may leak. 2. I like closing 2 lids to keep contents closed and closed; However, the outer cap is tight (which is welcome given the leak) but my son has trouble unscrewing it himself. All in all a good product, just wish the ring wouldn't fall off.
