I purchased both the sizes. My biggest complaint is the material and quality . Don’t not buy the ONYX material . I had only used it a few times . The color comes off and scratches are everywhere on the container . I hand wash the bowls with a very soft cloth but yet they looks terrible after a few washes . For the amount of money you spend , you would think that the quality of these containers would be good . I don’t use them anymore . Unfortunately there isn’t any warranty on them and I could not return them.
