The Pearl Technology contained in every THERA°PEARL pack is a game changing innovation to a time-tested therapy. Created by a doctor who knew she could offer her patients something better than a bag of frozen peas, THERA°PEARL was designed to offer improved therapeutic relief. Whether chilled or heated, Pearl Technology conveniently holds its temperature for the doctor recommended time of 20 minutes and the ergonomically-designed wraps and straps conform to the body to deliver relief from your aches and pains. Far better than a bag of peas or a bag of ice or a hot pack, the THERA°PEARL designs and convenient straps hold our body part-specific wraps in place, allowing the user to move around normally during use. Easily pliable when frozen, Pearl Technology is cold enough to offer targeted ice therapy without sacrificing flexibility. Not stiff, jagged or uncomfortable, chilled THERA°PEARL packs stay smooth and soft on skin as they conform to deliver soothing relief. When conveniently heated in a microwave, Pearl Technology is the perfect solution to relax stiff muscles and encourage blood flow and healing. Delivering consistent heat therapy directly to the desired relief area without a mess, the reusable packs are combination therapy in one convenient product. Available to fit most major body parts, use THERA°PEARL on your face, eyes, neck, wrists, ankles, back, arms, legs, knees, shins, and shoulders.
