Collar Stays (sometimes known as collar bones, sticks, stiffeners, knuckles and tabs) are shirt accessories.

Collar Stays are smooth, rigid strips of metal or plastic, rounded at one end and pointed at the other, inserted into specially made pockets on the underside of a man's shirt collar to stabilize the collar's points. The stays ensure that the collar lies flat against the collarbone, looking crisp and remaining in the correct place.
