Hot Hands brand hand warmers are intended for single-time use and are not reusable. They are typically valid for 3-4 years after the manufacturing date, as indicated by the exposed "shelf life" date on the packaging. After being opened, the warmers are only suitable for several hours before they lose their warmth. It is essential to open only as many warmers as needed and to store the remainder in a cool, dry place to extend their shelf life. Keeping them in a vacuum-sealed container can help preserve their heat for a longer period. While there is no specific expiration date printed on the individual warmers, they generally should not be used beyond their "shelf life."
