The bag is strong enough to hold the wheel lock key, socket and spare eyelets for my motorhome. There is space for more items if needed. The zipper is high quality and doesn't look cheap. I ordered wheel locks for my ram so another bag would be perfect for storing the wheel lock key and grommets. I've been considering ordering another set of covers/locks for my wife's car, but who steels the wheels on the Prius? I have no complaints about the quality and the price of the bags.
