There were a lot of counterfeit Ball lids sold on Amazon. The standard size come in a Ball box made for wide mouth lids. The lids themselves do not have the Ball label on them.These are Ball brand lids from last year. There were lots of complaints here on BYC about their quality. I also need to check the rings; they might have some spots of rust on the inside.
I'm done with the Ball lids I had on hand and am going back to the ones I ordered from Filmore Container. Those have been great! I think I had one FTS in all of them, and it was caused by a tomato seed getting under the seal as they processed.
