Aluminum Sub Posture Collar
Allows the posture collar to remain put until you wish to take it off.
This 3-inch (7,6 cm) thick and tall curved posture collar is handmade of aluminum which will hold up to the struggling of the wearer. It forces the wearer to keep their neck perfectly straight with their chin out. It features a solid welded tri-ring on the front and a heavy locking buckle in back.
