Review on Pack Plastic REGULAR Mouth Mason by David Herrera

I thought these were white plastic caps which I already have but they won't screw in properly, the threads seem to have come loose a bit. The lid is screwed on, but then sits at an angle on the glass. My old ones fit just like other tin lids. I don't know what's wrong with them but I'm sick of them on my old blue cans and some new ones with the same issues, don't want them to start well and end crooked which to me would suggest it's likely not tight as it should be. I will not buy this brand again.
