The reusable ice maker is odorless and BPA-free. Do not fill the ice cube tray to the top, as the ice expands. This prevents water from spilling. Thanks to the flexible silicone, the ice cubes can be easily released and are individually removable. The cubes are decorative and keep whiskey, cola, and many other drinks cool for a long time. The ice cube tray is dishwasher safe. The large silicone ice cube mold is an essential accessory for any home bar.
