Freeze massive, slow-melting hollow ice cylinders custom-designed to fit 40oz insulated travel tumblers.

Standard ice cubes melt fast, watering down your iced coffee, tea, or soda long before you finish drinking. Plus, dropping regular ice into narrow tumbler openings can be a hassle. The Cylindrical Silicone Ice Mold is specifically engineered to freeze large, hollow ice rings that stack neatly inside 40oz tumblers, keeping your drinks icy cold for hours without diluting the flavor.

Custom Fit for 40oz Travel Mugs

This clever silicone mold creates 3 distinct sizes of hollow ice cylinders that stack together perfectly around your tumbler’s central straw. Because the ice sits as a solid vertical cylinder rather than small loose cubes, it provides maximum surface cooling with a significantly slower melt rate—ensuring your iced drinks taste fresh from the first sip to the last.

Flexible Silicone with Protective Lid

Made from flexible, food-grade silicone, releasing the frozen ice cylinders is completely effortless. Simply push from the soft base to pop out intact ice rings without breaking them. The included snug-fitting lid prevents water from spilling in your freezer while sealing out unwanted freezer odors so your ice always tastes clean and fresh.

Infinite DIY Refreshment Options

Don’t stop at plain water! Fill the mold with coffee to make slow-melting iced coffee rings, freeze fruit juices and lemonade for summer punches, or add mint and fruit slices to elevate your daily hydration. It’s a must-have accessory for anyone who relies on their 40oz travel tumbler during long commutes, outdoor workouts, or hot summer days.
