Introducing the Rhewatin Tumbler Ice Tray, a specially designed ice cube tray that caters to the needs of 40oz tumblers. This innovative product offers three different sizes of hollow cylindrical ice cubes, allowing you to stack them within your tumbler to perfectly fit its shape. The larger and thicker ice rings melt much slower than traditional ice, keeping your beverage chilled and refreshed throughout the day.

Crafted from food-grade silicone, the Rhewatin Tumbler Ice Tray is non-BPA, dishwasher safe, and odorless. The flexible yet sturdy material ensures the tray can withstand freezing temperatures without cracking or breaking. Moreover, the included no-spill bin and lid allow you to fill the tray with water without any messy spills, and keep the water from splashing out in the fridge, as well as prevent odor contamination.

One of the key advantages of the Rhewatin Tumbler Ice Tray is its versatility. It is compatible with a wide range of 40oz tumblers, such as those from popular brands like Stanley, Yeti, Simple Modern, HydroJug, IRON °FLASK, and BrüMate. This means you can take your favorite tumbler with you wherever you go, and enjoy chilled drinks for up to 18 hours, thanks to the superior ice cube performance.

Compared to general ice cube trays, the Rhewatin Tumbler Ice Tray boasts several unique features. The larger ice cubes last longer, ensuring your drinks stay chilled for extended periods. The hollow cylinder design also prevents the ice cubes from getting stuck on the straw, and eliminates the annoying sloshing sound that can occur with traditional ice cubes.

Using the Rhewatin Tumbler Ice Tray is a breeze. The flexible silicone material makes it effortless to remove the ice cubes. Simply let the tray sit for 30 seconds after removing it from the freezer, and push the ice cubes out from the bottom – they'll pop out with ease.

With its exceptional performance, versatility, and user-friendly design, the Rhewatin Tumbler Ice Tray is the perfect companion for your 40oz tumbler, keeping your favorite beverages chilled and refreshed for the long haul.
