I agree I will be sending them back. I really can't see any black spots and they are tightly wrapped in plastic wrap so it is hard to tell if there is a coating. Has anyone seen white sealant on lids before?
Ok, so in my panic moment I ordered on Amazon the only lids I could find and this is what I got in the mail.
I have never seen white rubber seals before. and this here is the package it came in, I don't know about them. Any experiences with this type?
