Using this ice box is a breeze. First, open the grey cover and fill each of the 14 compartments with water. Then, place the ice box in the freezer. Wait for a few hours until the water turns into ice. When you need ice, just take out the box and remove the ice cubes. For cleaning, use mild soap and warm water. Make sure to dry it thoroughly before storing. Don't use sharp objects to scrape the ice box as it may damage the PE material. Also, keep it away from direct sunlight and high - temperature areas to maintain its quality.
