What to know before buying
Listing details to confirm
The listing calls the warmers reusable in one specification field, but its usage guidance says single use and disposal after use. It also gives the duration as both 24 hours and 24+ hours, and the maximum temperature and warmth duration depend on conditions. Use only in gloves or pockets, avoid prolonged skin contact, and remove immediately if it becomes too hot or irritation occurs. Follow the supplied cautions, including not using while sleeping, on children aged 0–6, or for medical treatment. Check the printed expiry date and storage guidance.
