Authentic Cervical Denneroll Orthotic Device purchased from a licensed chiropractor- not a dupe! This is a simple, yet complex, pillow-like device engineered with curves, angles, and ridges extrapolated proven to rebuild the c-curve in the cervical spine and correct “tech neck”. The Medium Cervical Denneroll for average adult populations or taller adults with limited range of motion in the cervical spine. The Medium denneroll has been sized for the dimensions to fit the typical adult cervical spine for adults that are approximately under 5 feet 9 inches in height. Excellent like new condition! Used only twice. (please use only under supervision of your doctor) Smoke free home :) New to Poshmark? Use code LAPALOMATRADING for $10 off 🙌🏼
