Silicone Sleeve for Regular Mouth Half Pint 8oz Mason Jars

$3.99 USD - $21.99 USD /
Subscription -

Upgrade your 8oz regular mouth Mason jars with these flexible silicone sleeves designed for everyday use. They provide a secure non-slip grip, added cushioning against bumps, and light insulation to help maintain temperature.

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 breaking. These versatile sleeves turn your glass jars into safer, more comfortable containers to handle.

Made from food-grade silicone rubber, these sleeves are durable, reusable, and safe. They’re dishwasher, microwave, and freezer safe.

1 sleeve per order. Jar not included.

Product Description

Easy On & Off Design: Features a small hole at the bottom to make removing the sleeve simple and hassle-free. 

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.
