Mason Jar Lifestyle
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.
Our kids use most of the half pint jars that are always littering the kitchen, but I also use them to drink coffee and cocktails.
Use a different color for each family member, and stop wondering which beverage cup is yours!
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.
They have a hole in the bottom to make getting them off easier.
You could also use one to block sunlight or prying eyes from the contents of your jar.
Great for kids and adults!
