Using this food storage jar is easy. Just open the lid, put your food inside, and close it tightly. You can store dry goods like nuts or cereals, or even wet items like jams. When it comes to cleaning, wash it with mild dish soap and warm water. Avoid using abrasive cleaners as they may scratch the glass. Keep it in a cool, dry place when not in use. Don't put it in the microwave or oven as it's made of glass and may break. Also, be careful when handling it to prevent dropping and breaking.
