We have redesigned these sleeves to eliminate the inside groove that runs around the top. The older style clips onto the glass bead or rim, just under the jar threading. This makes them a little more secure once on, but harder to get on and off. The new style is tight on current production Ball jars but a little loose on Kerr jars.
I drink my coffee from a wide mouth pint jar every morning. My silicone sleeve keeps my hands safe, and if I need to leave the house I screw on a wide mouth silicone drinking lid.
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.
You could also use one to block sunlight or prying eyes from the contents of your jar.
Great for kids and adults!
