Newest design, without a groove at the top.
Remove the sleeve by holding the jar by the threads and pulling on the hole in the bottom.
Silicone will not stop condensation from forming on a cold beverage in high humidity.
Use a different color for each family member, and stop wondering which beverage cup is yours!
I drink my coffee from a wide mouth pint jar every morning. My silicone sleeve keeps my hands safe, and when I take the kids to school I screw on a wide mouth silicone drinking lid.
Microwave safe means you can heat up your beverage without removing the sleeve. Or take out a frozen jar of food, put a sleeve 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!
