Fast Aid Heat Pads are thin enough to wear discreetly under clothes and can be applied directly to the skin or, if preferred, onto under garments. The pads are odour free, with none of the associated unpleasant smells of topical soothing creams and gels. Unopened pouches can be carried in the pocket or a handbag and used when required. Fast Aid Advanced Heat Pads are supplied in professional blue and gold packs, designed for use by all the family.
