•Each ice cube tray is composed of an ice tray and a lid with a small hole that also has a unique snap design to make each round ice ball regular and perfect. Simply rinse the circle ice cube mold under the water tap and fill the water in. No need to pour water into one hole after another. After filling, close the lid and place it in the freezer for at least 4 hours.
•This round ice cube tray is made of highly elastic-plastic which makes circle ice cubes easier to release than silicone ice cube molds. After taking the ice tray out of the refrigerator, twist and open the upper lid, and easily twisting the bottom ice tray, the circular ice cubes can be easily released.
