These lids are quite good, my original ones broke. You have to be extremely careful when you are placing your orders and this is something that the seller does not tell you. They are packed in a set of 4. I think it should be added to the advertisements. I bought a quantity of 6 thinking that I was just buying 6 lids and I ended up having 24 lids and I don't know what to do with the rest. It's a nightmare.
