TheraPearl provides dual action hot/cold packs for the therapeutic relief. The Pearl Technology® contained in every THERA°PEARL pack is game changing innovation born of an age old therapy. Crafted by a doctor who knew she could offer her patients something better than a bag of frozen peas, THERA°PEARL was designed with you in mind. Whether chilled or heated, Pearl Technology conveniently holds its temperature for the doctor recommended time of 20 minutes and conforms to your body to deliver the perfect relief from your aches and pains. Easily pliable when frozen, our Pearl Technology is cold enough to offer targeted ice therapy without sacrificing flexibility.
