Silicone Sleeve for Wide Mouth Half Pint Mason Jars


These silicone sleeves for *wide mouth* half pint (8oz) jars (short and wide, kind of bowl shaped) add grip and padding, and they also insulate. Use them for baby food, coffee cups, condiment cups, oatmeal, snacks, or anything else.

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 100% 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.

I make big batches of steel cut oats and store them in individual wide mouth half pint jars in the fridge. Then in the morning, I use this sleeve and microwave the jar for a quick and healthy breakfast for my kids (and sometimes me). The silicone sleeve adds grip, looks great, and I love the feel of it in my hand.

We designed the sleeve to fit tight enough that it won’t fall off, but loose enough that it is still easy to get on and off.

Use a different color for each family member, and stop wondering which jar is yours!

This size does not have a hole in the bottom, so you can also use it without a glass jar inside.

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.
