Silicone Sleeve for Regular Mouth Half Pint 8oz Mason Jars


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.

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.

Mix and match colors!

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!

As described. Work great!

My toddler has been using the 2 sleeves we got, as well as myself, at times. I love the happy colors, as well as the neutral options we can pair with his bright colored straws, or just a clear drinking top from this site. They are good quality, and are holding up well, so far. The silicone is thick enough that I feel like it will insulate well in the case of any drops, and I love having the option of non-toxic cups for him, without much risk of glass breaking. We had been (and still are) using sleeves from another company, which also worked well, but it is nice to have a slightly more reasonably priced option, with the convenience of ordering tops and sleeves from the same place!

Silicone jar sleeve

Good hand feel. Fits the jar I am using well. Thank you for another well put together and shipped order.

The silicone sleeve and silicone drinking lid were a gift for my smoothie-drinking child. A big hit! They'll be visiting the site for more mason jar goodies.

Great for little hands aka grandkids

I will let u know after next week when my grands visit us. They have plastic supply cups that Inwant to replace. I tried it with the sippy top and works for me in my regular pint ball jar.
