I should have paid more attention to the given sizes as these containers were very much smaller than I expected. The references in the blurb to keeping vegetables and greens fresh meant I just assumed they would fit a bag of salad greens or brocolli or other vegetable that wilted easily. However, they fit only most of a bag of coriander and such small items as tomatoes, so was a bit disappointed by that. But it was my fault for not noting the given size info. However, what I have put into the two containers I bought have indeed kept very fresh for a much longer time than normal. Especially the coriander which I usually find I have to throw out before I have finished the bag. So highly recommend for small items.
