Ice cube trays are made in what seems to be an unlimited number of shapes. While we love a lot of the cool ice cube trays that are available, this Ice Sticks Tray is the first one designed specifically for water bottles.
Most ice cubes are too large to fit into the opening of your water bottle, which is exactly why Progressive International created this solution. The set includes 2 trays (blue & aqua), both of which will make 8 frozen ice sticks that easily slide into any water bottle. When you’re done using them, just throw the flexible tray right into the dishwasher. [Purchase]
