Hedgehog Pocket Hand Warmer

This is a pocket hand warmer with a hedgehog design.
Purchased in December, it is brand new and unused.

[Product Description]

[Design]
This hand warmer heats up simply by pressing the metal disc inside the main body.
It's eco-friendly because it can be reused!

- When you bend the metal disc inside the hand warmer a few times, the liquid will crystallize and turn white, generating heat.
Once warm, place it in the cover to use.

- The liquid will not crystallize (and therefore will not heat up) in environments where the temperature is 20°C or higher.
Please use it in environments below 19°C.

- The hand warmer will stay warm at around 40°C for about 30 minutes, and the warmth will last even longer when placed in the cover.
The temperature and duration of warmth may vary depending on usage conditions.

To reuse:
- After use, wrap the hand warmer in a cloth or towel and place it in boiling water for about 10-20 minutes until the liquid inside the hand warmer becomes completely transparent.
Once it returns to a liquid state, cool it under running water, and once it has cooled down, it can be used again.
*Never heat the hand warmer in a microwave.
