Camp USA’s Pro Nut Set includes seven stoppers with the similar placement range as most nine-stopper sets. That suggests you’ll be able to have two fewer stoppers to fiddle with if you end up searching for placements. Every stopper has a curved profile with a grooved face for easier placing and cleaning, and Camp color coded the stoppers so you’ll identify the right kind size quicker.
