This BPA-free silicone tray makes four 2.25" square ice cubes for all of your beverage needs. Larger cubes melt slower, keeping your drink colder, longer. The included lid blocks out pesky flavors from your freezer and allows stacking of multiple trays. Frame made from rigid stainless steel makes filling and transporting the tray a breeze and the independent cube design made from flexible silicone allows individual cubes to easily be removed. This tray is freezer, dishwasher, oven and microwave safe so you can use it to bake mini treats as well!
