These Pyrex storage sets have 244+/- reviews of which 150 are 5*, and I
don't believe there is a 1*.
I have to admit that I use them a lot, but even though the lids are so tight
that I can't put them by myself, and the odors don't leak out, the lids
after removing contain the odor of my lasagna that I stored for less than 24
hours.

Soaking a little, then washing and drying, the lasagna odor persisted.

Probably a little baking soda will do it. I noticed that I did put saran
wrap on the other pyrex before I put on the blue pyrex lid. This is probably
the better idea.
