Product Description

Before these lids, we were using Ball plastic lids with a hole, a silicone grommet to hold the airlock, and a silicone sealing ring to make them airtight. Eventually the plastic would crack or break, and it was fussy to assemble all the pieces. This single piece of silicone replaces the lid, grommet, and sealing ring! They are easier to use, easier to clean, way better looking, and double as a tumbler lid when you aren’t fermenting anything!

For a complete lacto fermentation setup, pair this lid with an airlock and a glass weight. This will almost eliminate the chances of mold on your ferment. More fermentation instructions are coming soon, but for now they are widely available on blogs and other websites.

These will fit on any regular mouth jar – half pint, pint, or quart

Great for glass straws! Glass won’t clink against silicone.

Product Features

• Two Products in One! This lid and band for *Regular Mouth* (2 3/8″ internal diameter) Mason jars is both a straw hole tumbler lid, and also a lacto fermentation lid! The 10.5mm hole will accept any of our straws, and is also the perfect size for our fermentation airlocks!
• Rust Proof (Almost) Band Included – Standard Mason jar rings rust, but stainless steel will not rust with normal use. Both parts are dishwasher safe!
• Safest Materials – Food grade silicone rubber and 304 grade stainless steel are BPA free, non-plastic materials for food contact that do not leach any chemicals.
• Stylish – These lids look great anywhere, whether you are taking a smoothie jar to-go, or fermenting vegetables on your kitchen counter!
• No Clinking Noises – Metal lids can clink against the straw, but silicone is soft and silent.
