Review on Large Flexible 6-Cavity Ice Cube Trays for Whiskey and Cocktails - Keep Drinks Chilled (Pack of 2) by Karen Watson

This is an excellent ice cube tray for making large ice cubes for Roks. I was able to fill them almost to the brim without spilling anything on the way to the freezer. The ice cube can be easily pushed out from below because the material of the tray is flexible. The ice cubes are not a perfect square shape at the bottom due to the shape of the mold which has a slight angle at the corner. This does not affect the function of the ice cubes.
