Mason Jar Lids | Wide mouth 86mm | Plain White Plastic Lids

The new lids are equipped with a silicone seal housed within the lid. Please ensure that the silicone seal remains properly seated when closing the lid, as it may occasionally shift or fall out. A quick visual inspection before closing will help prevent any issues.

Will your lids fit all Mason jars?

Our lids are designed to fit mason jars labeled as Regular Mouth (70mm) or Wide Mouth (86mm). These are standard sizes, and they will fit popular branded jars like Ball, Kerr, Aussie Mason etc.

However, please note that non-branded jars from stores like Big W, Kmart, or Coles may not be the same size and our lids may not fit them.

Before purchasing, we recommend ordering a single lid to test the fit. You can also check your jar’s size by visiting the the website of the retailer where you purchased your jars or planning on purchasing the jar and confirming whether your jars are labeled Regular Mouth or Wide Mouth.

This way, you can be sure our lids will work with your jars.
