the largest jar is too big, it takes a lot of space in the fridge. The two biggest were cracked across the bottom so that the air space can not be done. Yet they have been manipulated in the rules allowed: dishwasher, fridge. We are much more satisfied with the set of 3 boxes, for against pity there was not a little bigger. Their material is more flexible I think they are more durable in time. I do not guarantee my crack problem.
