[Note: The sliding buckle cannot adjust the length of the elastic band.] You can slide the slider to determine the branching point or position of the elastic, which can better hold items of different shapes, but cannot adjust the length of the elastic. [Protective Effects] The surface of the hardened steel hook is enclosed in a thick plastic shell, which can protect your vehicle from scratches. [Rubber + Nylon] The elastic band is made of high-quality rubber and wrapped in nylon webbing. Good elasticity, good flexibility, not easy to deform or break. [Easy to Carry] For daily life or long-distance travel, you can attach the luggage strap directly to the vehicle. It can also be packed in a backpack without taking up too much space.
