I've thrown almost everything out because of this issue but wanted to come back and write a review to warn you. I've had them for a while and was very careful how they dried because I was always afraid the mesh would rust. And so it was. on everyone. Some had small spots, others were much larger. It is obvious that in both cases it is not safe to use them. I would look for something higher quality so this doesn't happen to you before you buy them. Such a waste of material and money. If you're like me and want to find a reliable option for your Keurig, stay away from them.
