EcoJarz classic stainless steel lids are entirely nonreactive and can be used with hot or cold beverages without any worry of chemical leach. The lid fits on any widemouthed mason or canning jar. With the use of a tin jar band, it turns into a reusable to-go cup. The product is made of stainless steel and FDA-grade silicone. Together with glass, EcoJarz lids mark the highest standard in no-leach drinking vessels. There’s no BPA, phthalates, or chemical leach. You can even reuse many glass jars from products such as salsa and almond butter.
A “Jar Band” is the tin ring that threads onto a glass jar, and it’s necessary to attach an EcoJarz lid. These drinking lids work just like a canning jar lid.
They’re made of 18-8 food-grade 304 stainless steel with an FDA-approved silicone gasket to prevent spills and leaks. The manufacturer recommends washing your new EcoJarz lid thoroughly with soap and water before use.
