How to use: First, put your daily items like books, clothes, and snacks in the main compartment. Place your laptop in the laptop sleeve to protect it. You can store small items like keys and chargers in the internal organizer. Use the side mesh pockets for water bottles or small tools. Attach your skateboard to the front skate strap with the plastic buckles. Adjust the padded shoulder straps to a comfortable length and use the integrated handle when needed. Attention: Remember that the skate deck is not included with the backpack. Don't overload the backpack beyond its capacity to avoid damage. Maintenance: To keep your backpack in good condition, clean it regularly with a mild detergent and a soft cloth. Let it air - dry completely. Avoid exposing it to sharp objects that could tear the polyester material.
