As the title suggests, this collar's main function is to make the wearer maintain perfect posture. The 3.5" height of the collar keeps the wearer's neck rigid, thereby forcing him or her to stand up straight. Handsewn in black leather, these serious disciplinary tools also have attached D-rings for leashes or chains. Collars are closed by means of two buckles on the back.
