The Zwilling box containers look nice, but they are unfortunately quite fragile. After 2-3 weeks of use, one of them had already cracked. I hand washed them before the first use and only stored rice in it. It's disappointing that these containers are so delicate and show damage so easily, especially given their price.

Love the idea of them but have found that many of them leak air. So causes me to obsess with checking all of them some are good others have to re vacuuming. Fridge ones don't leak
