Tiny Cup Use: Designed to double as a charming espresso cup, with a soft silicone sleeve that adds grip, comfort, and a pleasant feel in your hand.

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 Color Coding: Available in different colors so each family member can easily identify their own jar and stop mixing them up.

Versatile No-Base Design: This size has no hole in the bottom, allowing it to be used on its own or with a glass jar depending on your needs.

Microwave & Heat 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 & Maintenance: Typically just needs a quick rinse since it doesn’t touch the drink, and is also dishwasher safe; best cleaned separately from jars to avoid trapped water.

Fun for Pets Too: Perfect for making “pup cups,” adding an extra cute and practical use beyond beverages and food storage.

I use these as an adorable espresso cup. 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. 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!

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.

They make great "pup cups" too!!!
