Cold Cast, LLC makes a patented, latex-free finger-injury treatment wrap that combines cooling, cushioning and stabilization while leaving the wearer’s other fingers free to work, train or play. Its gel remains pliable when frozen, and the wrap can also be warmed for finger-joint stiffness and Raynaud’s symptoms. The company supplies individual users as well as organizations seeking private-label or logo-customized units, with orders ranging from 50 to 20,000 pieces.
