This such a nice little swivel snap hook (purse clip.) We had these manufactured to our specifications. We wanted something a bit smaller than other 3/4″ trigger hooks, but nice and substantial. It has a 3/4″ (20 mm) strap opening. The outside measurements are 15/16″ wide at the strap end, 1/2″ wide at the hook end, and 1-5/8″ long. Shiny rose gold / copper finish.
