Using your Ishiline food storage tank is easy. Just open the bamboo cover and put your food, like grains, into the tank. Close the cover tightly to keep the food fresh. When it comes to cleaning, you can wash it with mild dish soap and warm water. Make sure to dry it completely before using it again. Remember, the tank can handle temperatures from -20 to 150 degrees, but avoid sudden temperature changes to prevent cracking. Also, because of manual measurement, there might be a 1 - 3 cm difference in size, and the color might look a bit different from the picture on your screen due to monitor and light effects. Keep it in a dry place to maintain its quality.
