Reusable EcoJarz Drinking Jar Lid. The lid that transforms glass jars into a reusable to-go cup. Made of 18-8 food grade 304 stainless steel with an FDA-approved silicone gasket to prevent spills and leaks. Jar not included. Metal rings are available to fit your canning jar, subject to availability.

This EcoJarz lid fits on a mason or canning jar with a two-part lid. If you do not have a two-part lid, metal rings are available to fit your canning jar, subject to availability. A metal ring (Jar Band) threads onto a glass jar and is necessary to attach an Ecojarz drinking jar lid. It works just like a canning jar lid. If you already have a jar band(metal ring) you are good to go, but if not you can add one to your order for just £1, see below.

Made of stainless steel and FDA grade silicone. Together with glass, EcoJarz lids mark the highest standard in no-leach drinking vessels. No BPA, phthalates, or chemical leach and plastic Free! Packaging is made from Recycled Paper.

We recommend washing your new Ecojarz lid thoroughly with soap and water before use. Dry your stainless steel lids and jar bands well after washing and store in a dry place.

For those preserving novices, canning jars, also known as mason jars are designed in a clever and useful three-part system. First, you have the glass cup. Next up you have the two-part lid consisting of the thin metal disc, which covers the top of the jar, then finally a metal ring (the screw section) that holds the metal disc in place, forming an airtight seal. This lid replaces the metal disc, transforming your mason jar into a travel glass.

What size jars do I have?
Canning jars come in two sizes, Regular Mouth (AKA Small Mouth) and Wide Mouth. Regular Mouth jars have a 2 3/8 inch (60 mm) inner diameter (and a 2 3/4 inch (70 mm) outer diameter), and Wide Mouth jars have a 3 inch (76 mm) inner diameter (and a 3 3/8 inch (86 mm) outer diameter).

Dishwasher safe. You can remove the silicone gasket from the stainless steel lid for deep cleaning.
