Teach Your Sub Correct Posture
What makes this collar unique is that it has 4 height adjustments built in. Posture training could not be made easier with this device. Start them off at the short or low setting and gradually move up the settings to regular and then tall to really keep their heads high.
Settings range from 4 inches high up to a neck stretching 6 inches! This is this tallest collar we have to offer.
