We love to use glass jars instead of plastic cups for our kids’ beverages, but there is always the worry that they will end up broken on the ground.

These silicone sleeves for Regular Mouth Half Pint (8oz) jars add grip and padding, and they also insulate.

Product Description

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!

Perfect!

I’m trying to rid my cupboards of plastic- especially for the grandkids! These are great for the small 6 oz glass ball jars.

Jar koozie

I love my jar sleeve/koozie. I’m thinking I’m gonna like it a lot more in the winter being as the sleeve gets warm but not hot, hot. I use mine mainly for coffee to take with me to work. I didn’t even know they made such as this or I would’ve had one a long time ago. Very satisfied and will be ordering more. Thank you.

Frost Silicon Sleeve

I love this sleeve. I bought to use on my glass coffee cup w/straw. Diameter said 2 3/4”. My glass is 2 3/4”. It was hard to get on, so I boiled water when it was half way on, and set it in it for a bit. Made it much easier to finish getting it on. Makes glass much easier to hold onto. Definitely recommend!
