Using this backpack is super easy. Just adjust the straps to your comfort and start packing your essentials for your adventures. When you're out and about in the dark, you'll love seeing Slappy's eyes glow. You can have some fun moving his mouth to change his expression. As for maintenance, use a soft, dry cloth to gently clean the backpack. Avoid exposing it to sharp objects that could damage the leather or the details. Don't submerge it in water, as it's made of polyurethane and other materials that may not handle water well. Keep it in a cool, dry place when not in use to keep it in good condition. And remember, it's an officially licensed product, so take good care of it!
