We love to use glass jars instead of plastic cups for our kids’ beverages, but there is always the worry that they will end up broken on the ground. These silicone sleeves for Regular Mouth Half Pint (8oz) jars add grip and padding, and they also insulate. 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 food grade 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. Multi Purpose - Coffee, beer, soup, salad - whatever you're sipping or snacking, they're all tastier from Mason jar! Add a drinking lid, or stainless steel lid & straw, to make a plastic free travel mug. Or add a leak proof lid and bring lunch to work or store bulk snacks in easy to go portions in the pantry. Perfect for adults and kids!
