Bulk REGULAR Mouth Canning Jar Lids ( approx.170 ct.)

I am not happy with these lids. I’ve noticed the lids are thicker than they used to be in past orders, not sure if that’s the reason. Each batch I made has 1-3 unsealed jars. I’ve had to resort to redoing the unsealed ones to see if they’ll seal, and sometimes it works, but not always. It’s frustrating to have multiple jars unsealed that I have to try to use the products asap in order to not waste.
