My kids love them I bought two of them.The bag falls over sometimes because of the stand.Sturdy and so cute !The handle broke 1 week after using it and it’s much smaller than it appears but my daughter was able to fit most of her books into itIt's a backpack with a small matching duffle bag which also came with a zippered glasses or pencil case. The unit is sized for a child, ten years old tops.The zippers all work.Overall it is cheaply made, and the wheeled plastic carriage will NOT take stress. As a backpack, it looks OK, but it will not hold up to heavy use and it was not made to carry heavy books.There are no instructions.There are 2 small screws to attach the handle to the carriage, which did not match-up to the drilled holes in the very fragile metal handle, so take that into consideration.The backpack slides over the handle, and there are two short straps on the bottom of the backpack that lock into the bottom sides of the carriage.That's it.In one of the videos, is shown a snapping flap that attaches the backpack to the handle brace, this backpack with the bow, doesn't have that feature.In other words, this is pretty much a very cute toy. For a sleep-over, not for travelingThe way the backpack connects to the wheels is terrible. Backpack keeps coming lose. I have had to staple the connections and still a problem. Complete waste of money
