There are two general kinds of septum retainers. There are staple-shaped ones that are made of either blackened niobium to be less visible or stainless steel (or occasionally glass). Second, a variety of plugs may also be used as septum retainers. Typically, one would use a single-flare plug with an O-ring groove (also known as a bullet in reference to septum jewelry) or a double-grooved plug with O-rings. Septum wearers at larger gauges may find these plugs to be more practical as they are usually more readily available and may be more comfortable. At larger gauges, staple-shaped retainers may simply become uncomfortable/annoying for some wearers due to the size of the ends that are tucked inside the nostril.
