I do like these.  They are conveniently light but not cheap or flimsy.  Tops seem ok but I haven’t put them to the test — yes they smell but it will go away in time.  I like the roundness, the sizes, the compact way they fit together.  I really like that they were under 20.  Everything went up in price in 2020 — I’m scrambling and hunting bargains to get the few things I want to add to my kitchen, my home and my wardrobe.  This was important to get at a good price — my neighbor says it’s a great price!  I wanted these sizes with lids at under 20, and Wayfair did it!  Thanks.
