Have you ever purchased an ice cube tray, filled it up, carried it to the freezer and water splashes out? The new OXO covered ice cube tray will prevent this from happening to you. How many times have you gone into the freezer and pushed out some ice cubes, only to see some yucky black specs in your ice. Have no fear, the OXO ice cube tray with the plastic flap is the key to perfect ice cubes. The ice cube trays stack great in the freezer! No spilling! The ice cubes come out easily. You can pop out just a few or the entire tray. Simply the best ice cube tray on the market! I enjoy making my iced coffee to take to work.
