Not worth the money
"This bento container only looks pretty. As a cold or hot food keeper it's useless. I primed as per instructions and after 5 hours the food was room temp. Yes I understand the variable, but the food was hot going in and it's not even winter. The container I got from 2 Dollar shop does a much better job. This should not be marketed as a cold/hot food container because it does not do the job."
