Made with durable cotton and stitched with elastic, we carefully designed these lids to stay in place on the jar, but easily slip on and off when you need them to.
The cotton fabric allows air to flow freely to your brew, while the elastic seals tightly around the lip of your jar to keep fruit flies and dust out.
Trust us, once you get one, you'll have a hard time going back to a cloth and rubber band!
100% cotton. Made in USA.
