Silicone Sleeve for Quart 32oz Mason Jars
These silicone sleeves for Quart (32oz) Mason jars add grip and padding, and they also insulate. These fit both regular and wide-mouth jars. We have tested current production Ball and Kerr jars, but they can’t fit all vintage jars.
The extra grip that a silicone wrapper gives the jar makes it feel much more secure in my hand.
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, 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.
