No more aluminum foil!
I can’t tell you how much frustration this product has saved me. I used aluminum foil for years to make my own spawn jars. They always let extra moisture in, would tear, cost me extra money to buy more foil. I’m done with it all. The only product I’ll use to cover my jars to make spawn are these. Very easy to use, easy to clean, very little moisture let in…. Just very high quality. Highly recommended!

Finally a cost effective alternative to aluminum foil.
Just did my first run with these and couldn't be happier! No more than a few drops of water underneath then foil wrap. They are best suited for a modded lid because you don't want to leave them on as a cover during spawn jars colonization. My old lids just had a punched hole for innoculation and I left the foil on as a dust cover. No complaints here!

Awesome and easy!
Love these silicone jar covers and wish I had gotten them sooner. Easy to use, no waste, and less time in prepping your grain jars. Mosy definitely recommended.
