Fowlers Preserving Jar Ring Size 4 - 12 pack

The Preserving Ring is the key to the sealing process and thus preserving success.

The ring provides an even, airtight seal enabling a vacuum, so that your preserves, may last for years.

We strongly advise that the rings be used only once and should be disposed of after opening processed bottles.

Re-use of  rings will hinder or prevent the sealing process, with potential loss of contents as a result.
