Originally developed for fermentation, this simple two-piece lid found another calling: turning everyday Mason jars into straw tumblers.
Match your jar: Regular Mouth fits regular mouth Mason jars; Wide Mouth fits wide mouth Mason jars. These sizes are not interchangeable. Choose by the jar’s mouth size, not its capacity.
Straw fit: The opening is 10.5mm and accommodates straws up to 10mm wide. Choose a straw length that suits your jar.
Food-contact materials: The lid is LFGB European-grade, platinum-cured silicone; the band is 18/8 (304) stainless steel. The lid and band are plastic-free and BPA-free.
Simple setup: Place the silicone lid on your jar and screw on the included stainless steel band. There is no separate straw-hole grommet to install.
Close the opening: The open straw hole can spill. Remove your straw and use the Silicone Plug with Straw Strap to close the hole; its strap holds the straw beside your jar.
Fermenting setup: Fit the 3 Piece Airlock into the opening for fermenting. For wide mouth jars, the tempered glass fermentation weight helps hold vegetables below the brine. That weight does not fit regular mouth jars.
