Usage instructions:
The hand warmer does not heat up immediately after opening the package, it requires a brief period of time to start the heating process after absorbing oxygen. Do not expose it directly to the air, such as leaving it on the table. When exposed directly to the air, the hand warmer can cool down more quickly than it should due to heat dissipation. It can be placed in a heat-insulating environment such as in your pocket and wait for the temperature to rise before taking it out to warm your hands. If the temperature drops, put it back into your pocket or keep your hands in your pocket for an extended time to maintain its warm temperature.
