Specification Brand : Mason Jar Lifestyle BulletPoint1 : 2 Pack - These lids and bands for *Wide Mouth* jars are both a straw hole tumbler lid, and also a lacto fermentation lid. The 10.5mm hole will accept any straw up to 10mm, and is also the perfect size for most fermentation airlocks. BulletPoint2 : Fits Wide Mouth Jars - Wide mouth Mason, Ball, or Canning jars are 3" internal diameter, and usually have “Wide Mouth” printed on them. Good jar sizes to use with this product are Pint (16oz), Pint & Half (24oz), Quart (32oz), and Half Gallon (64oz). BulletPoint3 : Rust Proof Bands Included - Standard Mason jar rings rust, but stainless steel will not rust with normal use. Both parts are dishwasher safe! BulletPoint4 : 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. Make your own plastic free tumbler with these lids and our straws and silicone sleeves. BulletPoint5 : Stylish – These colorful 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.

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 lower 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 jar – half pint (8oz), pint (16oz), and quart (32oz).
