These Tker Ice Cube molds are huge. Each tray has 8 molds for a total of 16 extra large cubes that measure 2" x 2" x 2". Two of these Ice Cubes kept my Ice Tea cold until it was completely gone and it wasn't watered down by the end of my drink. These would work great for a whiskey on the rocks. Instant chill when pouring over this size cubes.
These are a soft flexible silicone mold and the cubes come out fairly easy. They are made of BPA Free and FDA approved silicone. They are dishwasher safe too which makes them easy to clean. I am very happy with the size of these ice cube molds.
