These silicone sleeves for Regular Mouth Pint (16oz) jars add grip and padding, and they also insulate. We have tested current production Ball and Kerr jars, but they can’t fit all vintage pint jars.

Made of 100% 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.
