Silicone Sleeve for Wide Mouth Mason Jars

These silicone sleeves for wide mouth Pint & Half (24oz) Mason jars add grip and padding, and they also insulate. A Pint & Half jar is tall, with straight sides. Ball discontinued them, so we now recommend Azure jars.

We love to use glass jars instead of plastic cups, but there is always the worry that they will end up broken on the ground.

Whether you call it a Koozie, a Kozie, a Coozy, a Cozy, or just an insulating sleeve, it’s perfect for protecting your glass jar from breakage and your hand from cold or heat.

Made of silicone rubber and lined with a non-stick polyurethane coating on the inside, these sleeves are dishwasher, freezer, and microwave safe! Silicone is a safe, green, non-plastic (BPA free) material for food use that does not leach any chemicals.
