This is an exercise device to help chronic back pain. Super easy to use, you just place it under your sacrum, while lying on the floor, and do tiny little movements (see pics for the idea). Takes very little time, but the benefits are amazing.
My medical massage therapist recommended I try this, so of course I did. Sadly for me, my spine is too deteriorated to be able to use it. Oh well.
It is in pristine condition. New ones are now $75, tho I paid $80 for this one, plus shipping (it’s not on Amazon🙀😁).
First, visit www.pelvicclock.com. You’ll be amazed and intrigued if you have nagging back pain issues.
Then come back here and buy it from me!
Thanks for looking, and good luck with your pain issues, however you manage them.
