where the zipper come to the top, there is a large black hook, about 1.5 inches and strap. What is this for? When I unhook the strap I can then pull the zippers together. If not, I have to stick it inside the suitcase and zippers don't close together a couple inches.
Also, if I unhook it and bring the zippers together, there are no holes in the zipper to put some sort of lock through. I must not be using this suitcase right.
