Posture Collar w Lace-Up Back
The idea behind this collar design is that if poor posture is assumed, a great discomfort is felt where the pointy bit pokes into the chest. The reflext is then to adjust the chin height back to proper posture. This produces well-behaved submissive and encourages improved posture for any human.
For fitting purposes, the lace allows the collar to fit any neck size. Additional lace could be interchanged at varying lengths for fashion or even wider necks.
The collar material is leather and hardware is steel.
