NICE SIZE -- 4 ice cube trays with lids, 14 ice cubes per tray for a total of 56 (the capacity of each cube is 27ml). Ideal for home use, baby food, parties, festivals and bars etc. SUPER EASY TO REMOVE ICE CUBES -- The bottom of the flexible ice cube trays is made of silicone. Each dice compartment is separate from others. So the ice cubes are very easy to loosen. No hard bending or twisting required. LEAKPROOF AND STACKABLE LID -- As for the lid's good sealing, can effectively prevent the water from overflowing, but also prevent peculiar smell between the foods.
