3 stars because they do hold stuff, and I think I'm being generous. Many reviews complain of broken glass on receipt but mine were all ok, nothing broken. The bad parts, though, is that the quality just sucks.
2 lids out of 4 looked like they been rolled in dirt before painting. They were rough and you could see the strands of dust and dirt under the paint. The other two were reasonable smooth as you'd expect.
The lids aren't threaded to go on the jars; there's a plastic insert that has the threads and it doesn't come out for cleaning. That means there's a fine gap that can collect nasties and can't get cleaned.
The red "can" that goes over the glass jar that makes up the canister is glued on with something, I'm guessing, similar to elmer's glue because if you wash the canister, by hand, it gets wet and turns white and, in my case, a week later and still white. So if you see through the glass between the jar and the can, it's gross with white blobs of glue. That means they're kind of gross looking on the counter.
It functions but I sure wish they'd been better quality.
