QRP REGULAR and WIDE MOUTH SEALS for Standard Size Mason Jars
- ALL QRP products are made from USDA Food Grade BPA-free Compliant Silicone and are produced by a reputable food container manufacturer for food products only.
- QRP SEALS STAY PUT. They are designed wide enough that they seat firmly against the roof of any brand Mason jar plastic cap completely underneath the threads and cannot fall out while screwing the lid onto or off the jar. And they are thick enough that they don’t wrinkle while tightening. Easy removal for easy clean; clear silicone aids in cleaning inspection.
- QRP SEALS provide a perfect airtight, anaerobic enclosure while fermenting Kimchi (vegetables) or Kombucha (tea).
- Lids not included.
