they have glue (where they glued the stainless to the glass jar) along the edges of a couple of the canisters. The glue actually broke free on one, so the stainless part slides down, and one of the lids doesn't thread on correctly. If I would have purchased this is a store, I would have tried to exchange them for a neater set, where all the lids screwed on tightly. I don't know if I just got a bad batch or what.
