Using this lunch bag is a breeze. Just unzip the double - zipped opening to put your food inside. The carry handle makes it easy to take with you wherever you go. You can write your name on the name tag to avoid mix - ups. When it comes to maintenance, since it's made of wipe - clean polyester, simply use a damp cloth to clean any spills or stains. Keep it away from sharp objects to prevent tears. Also, avoid overstuffing it to maintain its shape.
