Silicone Sleeve for Regular Mouth Half Pint 8oz Mason Jars

Secure Yet Flexible Fit: Engineered to fit snugly so it won’t slip off, while still stretching enough to be easily put on and removed from a variety of jar sizes.

Family-Friendly: Available in different colors so each family member can easily identify their own jar and stop mixing them up. You can also use one to block sunlight or prying eyes from the contents of your jar.

Microwave & Heat & Freezer Safe: The sleeve can stay on while microwaving, making it easy to heat drinks or warm up frozen jarred food safely and conveniently.

Easy Cleaning & Dishwasher Safe: These typically just needs a quick rinse since it doesn’t touch the drink, and they are best cleaned separately from jars to avoid trapped water. They are dishwasher safe though so you can toss them into your normal dishwashing rotating. You can leave them on the jar, but I find that water gets trapped so I prefer to separate them to clean the jar.

Whether you call it a Koozie, a Kozie, a Coozy, a Cozy, or just an insulating sleeve, they help protect against breakage while shielding your hands from heat and cold.
