Thank you for viewing. This is the Meteor Smart Kid's Belt, which can be used in place of a child seat simply by attaching it to the seatbelt. Applicable weight: 15kg to 36kg Approximate age: 3 years to 12 years Universal: Group Ⅱ & Ⅲ The box is torn, but the belt, storage pouch, and instruction manual are all included. It has never been used since it was opened, so it is an unused item.
