Silicone Straw Hole Tumbler with Stainless Steel Band for Mason Jars


Dual use! These lids function as both a straw hole tumbler lid, and also as a fermentation lid! The 10.5mm hole will accept any straw up to 10mm, and is also the perfect size for plastic 3 piece fermentation airlocks!

Attach with the included stainless steel band! Unlike normal Mason jar rings, this one will not rust with normal use and is dishwasher safe.

Made of food grade silicone rubber, these lid inserts are dishwasher, freezer, and microwave safe. Silicone is a safe, green, non-plastic (BPA free) material for food use that does not leach any chemicals.

One silicone straw hole lid and one stainless steel band / ring per order.

We set out to develop an all silicone fermentation lid, but quickly realized it would work just as well as a straw hole lid!

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. More fermentation instructions are coming soon, but for now they are widely available on blogs and other websites.

Made from 100% food grade silicone rubber and 18/8 304 grade stainless steel.

Exactly what I wanted

After searching various A-Z online retailers I finally came across this gem of a lid - it does exactly what I need it to do, has the right size straw hole for my needs, and best of all comes in two pieces for easy cleaning. Nothing complicated, just what I wanted! 10/10 perfect lid.
