attaches to car head rest to hold bags (LOVE LOVE LOVE LOVE these!) I got a two pack so one for each vehicle & it they have been SOOO handy to keep my purse in place during stop & go traffic! It is a large enough hook that several bags can hook on them like a gym bag, purse, & diaper bag all of which we use frequently. The only down side is that the small rubber pieces on the ends (mine were black) fell off in the first week or so with both - but they weren't that important really. Great buy!
