Original German quick release collar studs used frequently on officer's uniforms for the collar liner and also used on dress shirts with removable collars. The price is for a lot of 6 studs on the original paper card. This model has a button on one side and fold out wings on the other which are slightly held in place by tension. A very interesting accessory which can be very difficult to find. In the past, I have only ever come across a couple at a time, so having 6 matching ones in like-new condition is great.
