BORMIOLI Rubber Rings - Large, Set of 6

Replacement Rubber Rings for Fido Glass Jars - 3 3/4'' Diameter

The large rings fit Fido jars 500 ml and up

Tip: extend the life of your reusable Fido jars by removing the rubber seal before placing the jars in the dishwasher. It's also a good idea to replace the rubber seal before reusing the lid. You'll want to store foods with a high fat content in a different container, as fat tends to adversely affect the rubber seal
