Using your heart - shaped clear backpack is super easy. Just unzip the main compartment and put your stuff inside. You can carry it on your back with the adjustable straps. When it comes to maintenance, use a soft, damp cloth to wipe the PVC part clean. Avoid using harsh chemicals as they may damage the material. Keep in mind the California Proposition 65 warning. If you're in California, be aware of the potential chemical exposure. Also, don't overstuff the backpack as it may cause the shape to distort. Have fun using your backpack!
