These silicone sleeves for Half Gallon (64oz) Mason jars add grip and padding, and they also insulate. Designed for current production Ball jars - they don’t fit all vintage jars. They fit loosely on Azure jars and fall off easily.
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.
They are perfect for pitchers for 1/2 Gallons of milk, juices, lemonade, iced tea & iced coffee.
Made of silicone rubber, 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.
Product Description
We designed the sleeve to fit tight enough that it won’t fall off, but loose enough that it is still easy to get on and off. Different brands and mouth sizes of jars will vary a little in size, but it should stretch to fit almost any of them.
Microwave safe means you can heat up your beverage without removing the sleeve. Or take out a frozen jar of food, put a koozie on it, and heat it up.
Since they don’t touch your beverage, I often just rinse them, but they are also dishwasher safe. You can leave them on the jar, but I find that water gets trapped so I prefer to separate them to clean the jar.
