No need to deal with rinsing. Made of nylon backpack-type cloth in violet. This is how the pad looks as you slip the two liners into the holder. Here is the pad with the liners inside. When you snap it around your panties, the smooth unseamed side goes next to your body.
Menstrual cycles vary greatly from woman to woman.
Most women use 6 to 12 day pads and 1 to 3 night pads. It all depends on your flow and how often you do laundry. Change your Glad Rags as often as you would change a disposable. If you're leaving them to soak, change the water daily. Then machine wash and dry them with your other laundry.
