Yes! HotHands are non-toxic, odorless, and rigorously tested for safety. The internal heating materials are sealed in a leak-proof pouch, so there’s no risk of skin contact. They’re safe for adults and children (when used as directed). Do not puncture, microwave, or ingest the warmers, and keep them away from flammable materials.
