Ice Cube Tray for Tumbler Cup 30Oz-40Oz, 4 Pcs Silicone Cylinder Ice Mold with Lid for Freezer, Easy Fill and Release Ice Maker for Whiskey, Cocktail BPA-Free. A tumbler ice mold that can create perfectly shaped ice rings. This design allows the straw to go down the center... no more blocked straws from crushed or cubed ice, and your drink stays chilled twice as long! Simply pour water into ice cube mold, cover, and freeze. Avoid overfilling. These ice cup mold cylinders melt slower than traditional ice cubes, keeping your drinks cold for extended periods without diluting them. Enjoy every sip of your beverage with ice that lasts longer and maintains the drink's original flavor.
