Acumed neckbands are made of soft elasticised black material and can be used for back and neck pain. The magnet is discreetly housed inside the band and gently contoured to follow the natural curves of the body. The size can be adjusted by means of a toggle fastener. This dual purpose fastener counter balances the magnet and provides a gentle rocking motion of the band.Worn for only a few hours during the day, the neck band will aid those suffering from back and neck pain. Fit loosely and the gentle swing of the toggle will sweep and caress the magnetic field on the affected part of the body.
