4oz Silicone Sleeves/Jackets for Protecting Small Ball, Kerr, Quilted Canning Jars by Mason Jar Lifestyle (Bright Blue, 2 Pack)
Brand: Mason Jar Lifestyle
Color: Bright Blue
This size does not have a hole in the bottom, so you can also use it without a glass jar inside.

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.

Different brands of jars will vary a little in size, but it should stretch to fit almost any of them.

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