They are a very handy and good lid, if you are realistic and don't expect them to last forever. I've ran mine four times so far and one of them is starting to show a bit of rust. It's completely economical considering what other lids are going for, when you really just need a few lids and none of them last forever.

These hold up great! Ran them 4 times so far!

The jar lids are high quality, come in easy to handle sealed packaging, handled sterilization perfectly, and arrived a day early.

Honestly, it was such a prompt service that I I were in trouble, I’m not calling Spider-Man, imma call Midwest Grow Kits.
